One of the biggest obstacles for call centers to manage customer experience is noise. Agents working in hybrid or remote environments battle barking dogs, keyboard clicks, and street chatter that disrupts professionalism and clarity. The AI noise cancellation for call centers helps remove background noise, improving voice fluency, and ensuring every interaction sounds calm, confident, and human. Industry estimates suggest that poor audio quality can increase average handle time (AHT) by 15–20%, as agents and customers repeatedly ask for clarification. When calls become frustrating, customer satisfaction (CSAT) scores drop—and even skilled agents struggle to sound composed. For QA teams, reviewing noisy recordings wastes analysis time and lowers scoring accuracy. That’s why modern contact…  ( 9 min )

When you start learning backend development, it’s easy to focus on features, getting APIs to respond, connecting to the database, or just making it all work. In my projects built with FastAPI, I follow a simple but consistent pattern for error handling. For Example: from fastapi import APIRouter from sqlalchemy.exc import SQLAlchemyError from app.logger import logger # custom logger from app.database import get_db from app.models import Student router = APIRouter() @router.get("/students/{student_id}") def get_student(student_id: int): try: db = get_db() student = db.query(Student).filter(Student.id == student_id).first() if not student: logger.warning(f"No student found with ID {student_id}") return {"error": "Student not found"} logger.info(f"Fetched student: {student.name}") return {"student": student.name, "email": student.email} except SQLAlchemyError as e: logger.error(f"Database error while fetching student {student_id}: {e}") return {"error": "Database connection failed"} except Exception as e: logger.error(f"Unexpected error in get_student API: {e}") return {"error": "Something went wrong, please try again later"} Here’s what’s really happening behind the scenes: Every error is caught from database issues to unexpected runtime exceptions. Logs are categorized info for successful events, warnings for missing data, and errors for critical issues. No internal crash leaks to the user. Instead, users see a clean, friendly response while I get detailed error traces in my logs. The logger I use writes all messages to a local file, but also integrates with CloudWatch for live monitoring when deployed. It’s one of those invisible systems that keeps everything steady. Over time, I’ve learned that a stable backend isn’t the one that never fails it’s the one that knows how to fail gracefully and tell you exactly why.  ( 7 min )

Python bytearray Overview bytearray is an important built-in class in Python that represents a mutable sequence of bytes. bytearray is similar to bytes, but unlike bytes, bytearray is mutable. # Create a bytearray ba = bytearray(b'Hello') print(ba) # Output: bytearray(b'Hello') print(type(ba)) # Output: ba1 = bytearray(b'Hello') print(ba1) # bytearray(b'Hello') ba2 = bytearray('Hello', 'utf-8') print(ba2) # bytearray(b'Hello') ba3 = bytearray(5) print(ba3) # bytearray(b'\x00\x00\x00\x00\x00') ba4 = bytearray([65, 66, 67, 68]) # ASCII: A, B, C, D print(ba4) # bytearray(b'ABCD') # bytes is immutable (will cause error) b = b'Hello' # b[0] = 74 # TypeError: 'bytes' object does not support item assignment # bytearray is mutable ba = bytearray(b'Hello') ba[0] = 74 # ASCII code for 'J' print(ba) # bytearray(b'Jello') ba = bytearray(b'Hello') ba.append(33) # ASCII code for '!' print(ba) # bytearray(b'Hello!') ba = bytearray(b'Hello') ba.extend(b' World') print(ba) # bytearray(b'Hello World') ba = bytearray(b'Hello') # Convert to bytes bytes_obj = bytes(ba) print(bytes_obj) # b'Hello' # Convert to string string = ba.decode('utf-8') print(string) # 'Hello'  ( 6 min )

When I interview new developers or review resumes, I keep hearing the same question: Did I pick the right first programming language? Some candidates list four languages, trying to prove they’ve explored everything. Others feel they picked the wrong one—learning Python instead of Java somehow set them back. From my experience building teams at Microsoft, Meta, and now Educative, I know that the real difference comes from what you build, not the language you start with. I’ve seen engineers start with C, JavaScript, or Python and still grow into great developers. The difference wasn’t the syntax. It was the habit of building projects, finishing them, and learning from each one. Choosing a first language is career-defining because the tech world is noisy.

The first time I opened Xcode to build an iOS app, I thought I’d have something in the App Store within a week. I had the idea, the excitement, and a “Hello, World!” running on the simulator. But then reality hit. Auto-layout was confusing, Swift’s optionals were tricky, and I had no idea how to connect UI elements to my code properly. After a week of YouTube tutorials and unfinished blog posts, my app never made it past the login screen. Years later, I gave iOS development another shot—but this time, with structure. I followed a proper course instead of scattered tutorials, and everything changed. I didn’t just understand Swift; I was building and shipping real apps.

In modern application development, it’s rare to find a single-service system. Most real-world applications rely on multiple services working together — think of a web server, database, cache, and message broker forming one cohesive stack. Managing all these containers manually can be messy. That’s where Docker Compose becomes your secret weapon. Docker Compose is a simple yet powerful tool for defining and running multi-container Docker applications. You describe your entire stack in a single docker-compose.yml file, and with one command, you can build, start, and stop everything — from your API to your database — like clockwork. Here’s why Compose is a game changer for developers and DevOps engineers alike: Simplified Configuration: Define your entire application stack in one YAML file. …  ( 9 min )

⚙️ How Cloud Computing Powers Modern Apps In today’s fast-paced digital world, apps and websites need to be fast, scalable, and always online.

AI Gone Wild: When Images Trick Machines Into Hilarious Mistakes Imagine a self-driving car mistaking a harmless yield sign for a red light, causing a traffic jam. Or a medical imaging system misdiagnosing a healthy tissue sample. These aren't glitches; they're often the result of subtly manipulated images designed to fool even the most sophisticated AI. The core concept involves crafting inputs – we'll call them "opposite attractors" – that are significantly different from typical data but still trigger the same output from a machine learning model. Instead of making tiny tweaks to an existing image to change the classification, we create entirely new images that fool the AI into seeing something familiar, even though it's visually far removed from the original object.

Create a PROMPT.md in your project root directory. Use it to store all the context necessary about your project for your agent to save yourself time from re-explaining what your project is or what your preferences and project level decisions are. Context is one of the hardest things currently when using LLMs. You're either telling the LLM what your project is in each chat, or the LLM gets lost in the sauce and forgets what it is your project is trying to accomplish, or how you're trying to accomplish it. Create a file in your project root that tells the LLM what it should know every time (you should even let the LLM write/update it also). There is a great talk by Elixir Phoenix create Chris McCord about how they are actively trying to make Elixir (and Phoenix) the best language to code with an LLM. They are mostly ensuring that it generates valid Elixir code like Enum.at(my_list, 0) instead of my_list[0] by defining Elixir syntax in a PROMPT.md file. He recommends to use that file as a base and expand on it. There's a good quote during the talk where Chris says something like: You can spend your time arguing about the morals of AI, or you can be 2-3 times more productive. You can be Michelangelo painting the Sistine Chapel, telling the assistants what broad strokes to make and do the stuff you don't want to do while you focus on the big picture and ensure the small details are right. Or you're a mangaka with assistants filling in cells, whatever. The skill of reviewing code and making sure your vision is followed becomes more important at all levels. Just because you are not hand typing every line of css, html, javascript, ruby, c++, whatever doesn't mean you aren't doing the thinking and solving the problems.  ( 6 min )

MERN Stack is a combination of four powerful technologies: MongoDB, Express, React, and Node.js. With these four tools, you can build modern, fast, and complex web applications. Let’s take a detailed look at the role of each component and what they can do together. 🗄️ MongoDB - Database: MongoDB is a NoSQL database that stores data in the form of documents. It works in a JSON-like format, which makes it very convenient to use JavaScript. You can store user lists, product catalogs, or any other type of data. Express.js is a minimalist web framework for Node.js. It simplifies server-side logic, such as routing and creating API endpoints. Express allows you to write a server quickly and in an organized manner. React is a library used for building user interfaces. It works on a component-based system, meaning you can create each part of your application separately and them combine them. This makes code reusable and easier to manage. Node.js allows you to run JavaScript code on the server. This enables the entire stack to use only one language - JavaScript - which simplifies the development process. 📱 Full-functional web applications 💼 Business applications (CRM, ERP systems) 🛒 Online stores (E-commerce) 📊 Data management systems (Dashboards) 💬 Real-time applications (Chat apps, notification systems) 🎮 Games and interactive applications With the MERN Stack, you can create powerful applications intended for the world using only JavaScript. By learning and applying this stack, you can significantly enhance your skills. 🔗 Connect: ibrohimbek.link  ( 6 min )

In my early days as a software engineer, I often wondered: how do teams migrate between databases without bringing everything down? It’s one of those invisible feats of engineering — moving millions of records, decomposing APIs, redefining schemas — all while users continue using the system like nothing happened.

What Is Full-Stack Development? (A Simple Guide for Beginners) If you’ve ever heard someone say they’re a full-stack developer and wondered what that really means, you’re not alone. In simple terms, full-stack development refers to the ability to build both the front and back parts of a website or web application — everything users see and everything that runs behind the scenes. Think of it like building a house: the frontend is the design, furniture, and paint that people see, while the backend is the plumbing, wiring, and foundation that make everything work smoothly. 🖥️ Frontend: What Users See The frontend is the client side of a website — the part users interact with directly. It’s what you see when you open a web page: the layout, colors, buttons, forms, and animations. Frontend dev…  ( 7 min )

Reasoning Under a Cloud: Making Smarter AI Decisions with Fragmented Knowledge Imagine an AI trying to diagnose a patient with incomplete medical records. Or a self-driving car navigating a road where sensor data is intermittently lost. How can these systems make reliable decisions when the facts are fuzzy? The key lies in building AI that can not just process information, but also reason effectively with uncertainty. The core idea is creating a structured argumentation framework. Instead of treating arguments as black boxes, we analyze their internal structure—the premises and rules used to construct them. Then, we can model uncertainty directly within these components. This allows the system to weigh the strength of an argument based on the reliability of its foundation. Think of it li…  ( 7 min )

When it comes to software development, quality can make or break a product. But one persistent myth keeps popping up: Quality Assurance is just another word for testing. It’s easy to see why, testing is the most visible part of the process, but QA is so much more. Think of it as the entire system of practices that keeps quality top of mind from start to finish. Yes, testing is part of it, but QA includes planning, design reviews, coding standards, documentation and continuous improvements that prevent problems from ever reaching users. It’s about building quality in, not just checking for bugs at the end. For decision makers, understanding this bigger picture is key. Seeing QA as a strategic end to end approach rather than a single task is what separates average software from products that…  ( 12 min )

The emergence of advanced AI models has made it necessary to create standardized techniques for supplying them with real-time, external, or domain-specific data. A technical specification known as the Model Context Protocol (MCP) outlines the client-server communication necessary to provide this context. An MCP server, an application in charge of exposing specialized data sources like issues from Linear, design files from Figma, or repository code from GitHub, communicates with an MCP client (such as Gemini or GitHub Copilot). The LLM can perform tasks and reasoning that would be impossible with its base knowledge alone thanks to this client-server model. This fundamental feature of providing context to models was initially put forth in architectures such as Anthropic's Ask to Ask (A2A…  ( 10 min )

Modern displays are more than just LCD panels and touch sensors. Between the layers that make up your smartphone, automotive dashboard, or industrial HMI, there’s a transparent film doing critical work — the Optical Clear Adhesive (OCA). This adhesive is the reason screens stay bright, responsive, and durable even in challenging conditions. In this article, we’ll explore what OCA is, why it’s used, and how it’s changing display manufacturing. OCA is a transparent adhesive film used to bond optical layers together — such as the cover glass, touch panel, and display module. Unlike liquid adhesives, OCA comes as a pre-cast solid sheet. During assembly, it’s applied under pressure and temperature to create a bubble-free optical interface between components. In simple terms: OCA replaces th…  ( 8 min )

Introduction. The Beating Heart of Intelligent, Autonomous AI Agents If you’ve ever written a for or while loop in programming, you already understand the core idea behind the Agent Loop. It’s a cycle a repeating process that continues until a condition is met. But when it comes to AI agents, this loop becomes much more powerful. It’s not just about iteration; it’s about reasoning, tool use, and autonomous decision-making. In the AWS Strands Agentic Framework, the Agent Loop is the engine that powers intelligent behavior. It continuously processes input, reasons through possible actions, calls tools, and generates responses all while maintaining context and adapting to new information. This post dives deep into how this loop works, its key components, and why it’s at the heart of model…  ( 9 min )

Introduction Random testing can explore broad state spaces but often leaves gaps. Directed tests provide structure but risk missing unexpected interactions. The most effective approach combines the two: constrained-random stimulus for breadth and directed suites for precision [2]. The Challenge: Random Alone Is Not Enough Directed suites can systematically validate those features, but cannot anticipate subtle corner cases. Together, these limitations highlight the need for a combined strategy. Random stimulus is used to discover the unexpected, while directed suites guarantee compliance with the specification [3]. Note that compliance is a necessary but not sufficient measure for verification. Constrained-Random Testing with STING Constrained-random test generation is often the starting po…  ( 11 min )

In the previous article, we introduced a PostgreSQL database to our forum, achieving persistent data storage, so that data is no longer lost even if the server restarts. Now we can confidently make more improvements. However, you may have noticed that all of our current interface styles (HTML) are written directly in main.py. Does this mean that for every new feature in the future, we have to stuff more HTML into main.py? This is not only troublesome to write, but it also leads to a large number of HTML strings being mixed into the Python code, making the code difficult to read and maintain. To solve this problem, this article will introduce the Jinja2 template engine to separate the backend logic (Python) from the frontend presentation (HTML), making the project structure clearer and easi…  ( 9 min )

Without Bitcoin ETF holding sustained inflows, Bitcoin could succumb to “demand side fragility,” analysts from Bitfinex warn.

VanEck’s Nathan Frankovitz and Matthew Sigel said if miners don’t keep investing in the latest machines, the share of the global hashrate deteriorates, resulting in reduced Bitcoin rewards.

ARK Invest-backed Quantum Solutions is now the largest Ether treasury outside of the US and has a 100,000 ETH treasury target.

Hyperliquid Strategies is looking to raise up to $1 billion by raising shares of common stock to fund additional HYPE purchases.

The prediction market is expected to be fully launched sometime in the fourth quarter of the calendar year.

Crypto analysts predicted Bitcoin could fall to its 50-week moving average before reversing, citing leverage concerns and historical support patterns.

T. Rowe Price, a $1.8 trillion asset manager, has made its first crypto play, filing to list a US-listed Active Crypto ETF, in a twist that surprised some analysts.

Several prominent Bitcoiners remain confident that Bitcoin will hit $250,000 by year-end, but Galaxy Digital CEO Mike Novogratz isn't so sure.

Young Australians feel they could have made a bigger dent in their property goals if they had invested in cryptocurrency 10 years ago, and now they’re locked out.

Polymarket will act as a clearinghouse for DraftKings’ upcoming prediction market platform, following its acquisition of Railbird earlier this week.

That was the final step in a process that began after a massive security breach last year froze assets, shuttered withdrawals, and effectively took India’s oldest crypto platform offline.  ( 29 min )

One of the leading architects of the current generative AI boom — Microsoft CEO Satya Nadella, famed for having the software giant take an early investment in OpenAI (and later saying he was "good for my $80 billion") — published his latest annual letter yesterday on LinkedIn (a Microsoft subsidiary), and it's chock full of interesting ideas about the near-term future that enterprise technical decision makers would do well to pay attention to, as it could aid in their own planning and tech stack development. In a companion post on X, Nadella wrote, “AI is radically changing every layer of the tech stack, and we’re changing with it." The full letter reinforces that message: Microsoft sees itself not just participating in the AI revolution, but shaping its infrastructure, security, tooling …

If you've heard the folk tale of John Henry, you know the story: a steel-driving man who raced against a steam-powered hammer to prove human worth and dignity. He won the race but died with his hammer in his hand. It's a powerful allegory about technological change, human pride, and the cost of resistance. Today, as AI coding assistants become ubiquitous in software development, many developers feel like they're staring down their own steam-powered hammer. The anxiety is real—will AI replace us? Should we resist? Are we racing toward obsolescence? But here's what the John Henry story often obscures: the steam engine didn't eliminate workers; it transformed work itself. The railroad industry exploded after mechanization. More tunnels were built, more tracks laid, more infrastructure created…  ( 16 min )

There is a quiet moment, just after a feature is "done," when you click a link and witness the browser's brutal ritual. The entire page—the meticulously crafted header, the complex sidebar, the persistent player—blinks out of existence. For a heart-stopping second, there is nothing. Then, it all rushes back, reassembling itself just to update a small counter in the corner. We've accepted this as the cost of doing business on the web. Our server renders a complete, holistic page, a single, indivisible block of HTML. But our users don't experience the page as a monolith. They experience it as a collection of independent components: a shopping cart, a live feed, a search result list. What if our technology reflected that reality? What if, instead of sculpting from marble—a single, heavy block…  ( 10 min )

liner notes: Professional : Today started off rough, but got better through the day. Totally forgot about a meeting because the company logged me out of Slack on my phone and I'm not able to log into my work calendar, so I got no notifications and was locked into coding. Speaking of coding, I got a demo started but ran into a road block. The good news, I think I know a way to get around it. Personal : Did a bunch of sketching and design for some stickers. I did some measurements and modified a model. I also went through some projects on Bandcamp that I plan to pick up this week. I thought of another prototype that I want to make to show the prospective client. Been thinking and researching the best way to be able to print it reliably. I'm thinking I may go back and put in a little bit of time in the demo I was building for work. I think a couple of hours tonight will save me a bunch of time tomorrow because I won't have meetings or people asking me questions and I'll be able to focus. Like I said, I think I have an idea of what I need to do to be able to get it to a good place to be able to demonstrate the idea. Yeah, I'll work on that and get back to putting together the social media posts for the Bandcamp projects and think and sketch more the prototype and stickers.

You’ve just been assigned to The Monolith. It’s not a pejorative; it’s a title earned through years of service. This Node.js codebase is the bedrock of your company—a sprawling, complex entity with layers of history etched into its very structure. You git clone, run npm install, and are greeted not by errors, but by a different kind of challenge: the weight of legacy. In the heart of this digital forest, you find trails overgrown with tangled functions, campsites littered with // TODO comments, and ancient, runic code that everyone is afraid to touch. The pressure is always to build the new feature, to hack in the hotfix. But you know that unmanaged entropy is a technical death sentence. This is where we embrace a different philosophy.

Building Streaky: A GitHub Streak Guardian Part 1: The Journey from "Simple App" to Distributed System I thought building a GitHub streak reminder would take a weekend.

I saw the original Isotope Javascript fancyness and I just had to write a rebuild using modern web standards. Check out my rebuild! My version of Isotope uses a grid layout and animates using view transition. It is silky smooth, blazing fast and has graceful degredation. The code consists of only 63 lines of vanilla JS, while the old version required an astonishing 3500+ lines. If you choose to leave the sorting out, you can even reduce the code to 37 lines. Yup... the web has come a long way. Just set id="isotope" on any container and give its children classes that represent categories, like class="metal". Then create some buttons with data attributes, like data-filter=".metal" or data-sortby="symbol". Load the JS from the demo in the footer and it works. You don't need ANY of the CSS. That is all just fancy stuff. Note that my version only supports basic filtering and sorting (which are the only things I ever used from the original code). Also note that the animations do not work in Firefox (yet). Finally, be aware that you can not use this Isotope filter twice on the same page, as it lacks abstraction for that.  ( 6 min )

⚠️ Warning: The "Overfitting to a Single Data Point" Pitfall In AI-powered media analysis, it's easy to fall into the trap of overemphasizing a single data point that may not be representative of the larger trend or dataset. This phenomenon is known as "overfitting to a single data point." It occurs when a model is heavily influenced by an outlier or an unusual observation, leading to inaccurate conclusions and flawed insights. For instance, consider a media analysis project where a model is trained to predict the sentiment of social media posts about a particular brand. If the dataset contains a single post with an extremely positive sentiment, the model may learn to associate the brand with an overly optimistic tone. However, this might not reflect the actual sentiment of the majority of the users, potentially leading to a biased perception of the brand's reputation. To avoid this pitfall, data scientists and media analysts must employ robust methods to validate their findings.... This post was originally shared as an AI/ML insight.

🧙‍♂️ Survival Engine Debug Log: Hands Slot Resurrection & Tooltip Bifurcation Ritual 🔍 Initial Problem: The Ghost of Hands Slot The Hands slot was a phantom. No sprite. No tooltip. No runtime truth. Clicking it felt like whispering into the void. Hovering? Nothing. Meanwhile, gear slots were living their best lives — fully wired, fully responsive. Hands was the neglected middle child of the UI hierarchy. 🧪 Phase 1: Interface Alignment & Shrine Purification GearSlotUI.cs was referencing ghost fields like GetRarity() and GetArmourValue() — banished.

Hey Dev.to community! I'm excited to announce the release of the Kiponos Python SDK v0.1.2 on PyPI! Kiponos is a real-time configuration-as-a-service platform that lets you manage configs dynamically via simple SDK. Internally built on WebSockets and STOMP, Kiponos provides instant updates across environments in zero latency!. It's perfect for AI apps, DevOps workflows, or any Python project needing zero-latency config changes without redeploys. without restarts. without even a refresh! Anything you modify online instantly affects your algorithm or any python app! simple as that! Real-Time Sync: Fetch the initial config tree and subscribe to delta updates (key created/updated) for instant reflection in your app. Local Access: Configs stored in memory for fast lookups (e.g., client.get("learning-rate") or client.get("timeout") etc. Secure & Isolated: Uses env vars for auth (KIPONOS_ID, KIPONOS_ACCESS) and supports profile paths for environment-specific configs. Simple Integration: Connect, fetch, and query with minimal code. Get started with: pip install kiponos-pysdk Requires Python 3.12+. Set up your env vars (from your Kiponos account): export KIPONOS_ID="your-id" export KIPONOS_ACCESS="your-access" Then: from kiponos_pysdk import KiponosClient # work on specific config profile client = KiponosClient(kiponos="['my-app']['1.0.0']['dev']['base']") client.connect() # Get a config value print(client.get("timeout", "not found")) # e.g., "100" client.close() For an interactive demo, check the repo for usage_example.py—it supports commands like get , list-keys, dump, and exit. Built over 3 years of development, Kiponos decouples config from code, making your apps environment-agnostic. Free plans available—sign up at kiponos.io to get your tokens. Feedback welcome!

Binary Hardening in Rust (and Beyond) Hello stranger of the internet, and welcome back! Rust developers have access to powerful binary hardening techniques that make reverse engineering significantly harder—from compile-time string encryption and control flow obfuscation to self-integrity checks and memory protection. These aren't theoretical concepts: they're practical strategies that raise the cost of tampering and credential extraction in production software. Binary protection isn't just paranoia, or maybe is... Every application that ships to untrusted environments—whether compiled binaries, bytecode, or bundled JavaScript—needs defenses against tampering, credential extraction, and reverse engineering. The difference between "some kid on Reddit cracked my app in 3 hours" and "determ…  ( 10 min )

Hi everyone! My name is Dmitrii, and I’ve been working as a frontend developer for the past 11 years. Over my career, I’ve had the chance to build a wide variety of web applications — from small startups to core, high-traffic products for some of the largest tech companies in the country. This is actually my first article ever and honestly, not the easiest topic to start with. But let’s see how it goes. I want to start a series of articles on a topic that has been on my mind a lot in recent years — frontend application architecture. Actually, this isn’t just about frontend — many of the ideas apply to software in general, regardless of language or platform. But since my experience is mainly in frontend, that’s the perspective I’ll focus on. Much of this will also apply to backend applicati…  ( 7 min )

Article Short Review Meta‑Awareness Enhancement in Large Language Models The article investigates the meta‑awareness of reasoning models—how language systems internally gauge their own problem‑solving processes. By demonstrating a pronounced misalignment between predicted meta‑information and actual rollouts, the authors argue that current large language models lack true self‑knowledge. To address this gap, they introduce Meta‑Awareness via Self‑Alignment (MASA), a training pipeline that leverages self‑generated signals rather than external datasets. MASA incorporates two efficiency strategies: filtering out zero‑variance prompts and truncating unlikely rollouts, thereby reducing computational overhead. Experimental results show significant accuracy improvements across in‑doma…  ( 8 min )

Building Reproducible n8n Environments with CLI-Based Configuration Management When you're building applications with n8n as a core component—not just using it as a standalone automation tool—you need a way to provision n8n instances with pre-configured credentials, workflows, and integrated services. This article shows you a pattern for creating fully reproducible n8n environments using the n8n CLI and environment variable substitution. Most n8n tutorials focus on getting started quickly. But what if you're building an application where n8n is one piece of a larger system? You need: Reproducible environments - Same setup across dev, staging, production Pre-configured credentials - Database connections ready to use Integrated services - PostgreSQL for data storage, Redis for agent memory…  ( 11 min )

For a long time, “protein” was almost synonymous with chicken, eggs, and whey shakes. But today, more people are realizing that you can build muscle, stay energetic, and maintain great health entirely on vegetarian or plant-based foods — as long as you know where to get your protein and how to balance it. Whether you’re vegetarian for health, environmental, or ethical reasons, this guide will show you how to meet your protein needs naturally. Why Protein Matters Protein isn’t just for bodybuilders. It’s the foundation of every cell in your body — from muscles and bones to skin, enzymes, and hormones. It repairs tissues, supports immunity, and fuels metabolism. The average adult needs roughly 0.8–1.0 grams of protein per kilogram of body weight daily, but those who lift weights or play spor…  ( 8 min )

Hello, I'm Maneshwar. I'm working on FreeDevTools online currently building *one place for all dev tools, cheat codes, and TLDRs* — a free, open-source hub where developers can quickly find and use tools without any hassle of searching all over the internet. If you’ve ever wondered how a browser engine works under the hood, Servo is one of the best open-source projects to explore. It’s a prototype browser engine built in Rust, focusing on performance, modularity, and safety — the same principles that power modern web tech today.

This week I focused on design and structure. Using Figma, I created the first wireframes for Event Hub 2025. Key decisions: Home page with event cards and filters Detail pages with event info and images Profile dashboard for managing events I researched UI inspiration from Dribbble and Behance, analyzing how modern event apps present data. This step helped me visualize how users will interact with the app. Next week, I’ll move to implementation using Next.js and TailwindCSS.  ( 6 min )

This week marked the official start of my project journey — Event Hub 2025. I wanted to create something meaningful that solves a real-world problem. I started by clearly defining the project goals, target users, and core features: Discover upcoming events easily Allow organizers to create and manage events Enable ticket reservations and image uploads I also created a Trello board for weekly milestones and opened a GitHub repository to track commits from the start. This week’s main outcome was project planning and motivation building. I now have a clear roadmap ahead!  ( 6 min )

You publish an article. It gets some views. Maybe a few reactions. But then what? DEV.to's built-in analytics show you the basics, but they don't answer the questions that actually matter: Which tags are driving the most traffic? Is my content getting better over time? Which old articles should I update? What's my actual engagement rate? Should I be using different tags? After publishing 16 articles and hitting 983 views, I realized I was flying blind. So I built DEV.to Analytics Pro - and the insights completely changed my content strategy. Using the tool on my own articles, I found some surprising patterns: My two articles about AI security averaged 116 views each - nearly double my overall average of 61 views/article. This completely shifted my content strategy toward AI + security topi…  ( 9 min )

Okay, let’s step back a bit. About two weeks ago, I was performing open-heart surgery on my production-grade Kubernetes cluster — I swapped out the storage backbone from Rook-Ceph to Longhorn. And I'm happy to report: the patient is not only alive but running better than ever. No theoretical deep-dive here—this is a raw, post-migration debrief from the trenches. If you've ever whispered the words "my storage is a bit... fragile," grab a coffee. This one's for you. Part 1: The "Why Now?" Moment Let's be real: I didn't just wake up and decide to rip out a core infrastructure piece for fun. Rook-Ceph is powerful. It’s like owning a Formula 1 car. But my needs?

Nowadays, when a user visits our website or web application using a mobile, tablet, or laptop — he should be able to use it comfortably. This is the main purpose of responsive web design. Responsive design means the layout, text, images, buttons, etc. will adjust automatically according to the screen size. 1. Mobile-First Approach We have to start our design with small screens like mobile. Then, gradually, we can expand the design for larger screens. 2. Viewport Meta Tag Usage In the tag of HTML, the viewport meta tag is required. The code looks like this: It helps the website become responsive according to the device’s viewport. 3. Using Max-Width for Layout Control and Center Alignment On large screens, the website content should not be too wide horizontally, and on small screens, it should fit properly and look good. .container { max-width: 1200px; margin: 0 auto; padding: 0 20px; } Every modern website uses this technique. 4. Relative Units and Flexible Layout We should use %, rem, or em instead of pixels. .container { width: 90%; } 5. Using Flexbox and Grid Layout In the past, people used float-based layouts, but nowadays, the simplest and most modern solution is using Flexbox and Grid. 6. Making Images and Videos Fluid We have to use relative units and avoid fixed pixel sizes for images. img { max-width: 100%; height: auto; } 7. Responsive Typography If the screen is small, font sizes should also be smaller; otherwise, they will look oversized. 8. Responsive Navigation Menu The navigation bar is one of the most important parts of a website. We can use media queries for small screens and convert the menu layout into a vertical one. Responsive web design is now a mandatory part of modern web development. If we can properly use HTML, CSS, Flexbox, Grid, and Media Queries, we can build websites that work smoothly and beautifully across all screen sizes.  ( 8 min )

🧩 1. What is a Constructor? A constructor in Java is a special method used to initialize objects. no return type. Example: public class Person { private String name; // Constructor public Person(String name) { this.name = name; } } Constructors are called when you create an object: Person person = new Person("Gaurav"); A default constructor is a no-argument constructor that Java automatically adds if you do not define any constructor in your class. Example: public class Employee { private int id; private String name; } The Java compiler automatically adds: public Employee() { super(); // calls Object class constructor } So you can still do: Employee e = new Employee(); // ✅ Works fine If you explicitly define any constructor (parameterized or no…  ( 9 min )

I built a minimal Spring Boot service for my HNG Stage‑0 backend task that returns a profile object plus a fun cat fact. The goal was to deliver a clear, runnable microservice in a few files so reviewers can quickly run and inspect the code. What it does Exposes GET /me Returns a JSON payload with status, a small user profile (name, role, links), a timestamp, and a cat fact fetched from https://catfact.ninja/fact Architecture (short) ProfileController — handles /me and returns a ProfileResponse DTO. ProfileService — builds the profile and fetches the external cat fact using Java HttpClient. Profile (domain) and ProfileResponse (DTO) — simple POJOs for shape and serialization. Spring Boot entrypoint and a single minimal unit test to ensure application context loads. Why this shape? Minimal surface area: reviewers can audit the domain, controller, and service quickly. External call isolated in the service so it’s easy to mock or replace. Small codebase is ideal for early-stage tasks and focused feedback. How to run locally From the project root (uses the included Maven wrapper): ./mvnw spring-boot:run Then open: http://localhost:8080/me What I learned / next steps Keep services focused and small for fast review cycles. Inject HttpClient (or a wrapper) to make the external API call testable and mockable. Add structured error handling and logging for robustness. Add unit tests that mock the cat-fact API and an integration test for the controller. check the repository: here  ( 6 min )

On October 20, 2025, one of AWS’s largest data centers in Virginia went dark. A DNS failure during a DynamoDB API update cascaded into a massive global outage, crippling over a thousand services - from banking apps to crypto networks like Coinbase, Base, and Infura. It was another reminder that almost everything online, even “decentralized apps,” still runs on someone else’s computer.​ AWS had become the beating heart of global infrastructure. So, when it stumbled, the internet staggered. But what truly caught the crypto industry’s attention wasn’t that Coinbase or OpenAI went dark - it was that Ethereum access through Infura also went down.​ That led to an uncomfortable question: if blockchain is supposed to be decentralized, why does a bug in one AWS region bring half of Web3 to its knee…  ( 9 min )

Hi everyone, I'm facing a lot of issues — there are many models, many open-source ones, and many others that are quite costly — but none can guarantee that 100% (or even close) of the data will be extracted correctly from my PDFs, DOCX files, or other formats. I also have another problem: I'm Italian and want to build this for an Italian audience, so the documents will be in Italian — and some extractors don’t handle that very well.

I get that desktop applications are out of style these days. But they are still a good way to deliver powerful features and high performance graphics. However, delivering modular Java applications on Windows is a challenge. It almost seems like Java and Windows have conspired against each other. Java requires that all module jars are listed in one command line parameter. That works fine when Unix shells have a >100K character command line. Windows batch files have a relatively short limit (8191) on the lengths of their command lines. This makes it impossible to launch large-ish modular Java applications on Windows using the standard scripting model of every parameter on the JVM’s launch command line. The work around is to specify an argument file (e.g. @app.args) when launching Java.…  ( 10 min )

**Sean Fennessey and Chris Ryan kick off their horror deep-dive with juicy headlines—from a Nolan trailer tease to casting scoops for Behemoth!—before tearing into Scott Derrickson’s disappointing The Black Phone 2. They then riff on why horror feels a bit off in 2025 and count down their top ten fright-fest favorites of the year. Later, Alex Ross Perry joins to spill the beans on crafting his V/H/S/Halloween segment, stressing that personal fear is the secret sauce, and the trio wraps up by dissecting what makes a horror anthology truly terrifying (plus their must-watch picks).

By Humphery Otuoniyo I built a RESTful API service designed to analyze strings and store their computed properties. The project offered a hands-on experience in backend development, from schema design to deployment on Railway, and highlighted the importance of robust data validation and flexible querying. The service analyzes any submitted string and computes several properties: Length: Number of characters in the string Is Palindrome: Boolean indicating whether the string reads the same forwards and backwards (case-insensitive) Unique Characters: Count of distinct characters Word Count: Number of words separated by whitespace SHA-256 Hash: Unique identifier for the string Character Frequency Map: A dictionary mapping each character to its occurrence count This allowed the service to not o…  ( 8 min )

Everything Wrong With Every Saw Movie EVER (That We've Sinned So Far) CinemaSins takes on the entire Saw franchise, counting every single “sin” and cinematic hiccup from Jigsaw’s bloodiest saga. They’ve packed the video description with links to their main site, YouTube channels (@TVSins, @CommercialSins, @CinemaSinsPodcastNetwork), a sinful poll to learn more about you, and a Patreon page if you want to fuel their film-grading addiction. Shout-outs go to their sin-slinging writers (Jeremy, Chris, Aaron, Jonathan, Deneé, Ian, Daniel), plus all the social hangouts—Discord, Reddit, Instagram, TikTok—and even Jeremy’s book for those who can’t get enough of CinemaSins’ witty tear-downs.

I’ve been doing the job hunt all wrong. Like many of you, I’ve been on the hunt for a few months now and it can be exhausting. Sending application after application and hearing nothing back is demoralizing. A few weeks ago, I attended the Commit Your Code tech conference in Frisco, TX, and it truly changed everything for me. I met an incredible community of developers helping each other learn, grow, and navigate today’s job market, especially through the 100Devs and CYC Discords. I’ve been in the industry for over six years, but the most important thing I’ve learned recently wasn’t technical — it was personal. Back in 2021, when dev demand was at an all time high, I was spoiled. I didn’t have to apply for jobs. A friend made an intro, I interviewed, and BOOM, hired immediately. For better or worse, that market’s gone now, and for a while, I was still acting like it wasn’t. I’ve had to accept that I can’t take employability for granted anymore. The game has changed. I need to be proactive in new ways: by networking intentionally, building real connections, and creating a visible online presence. This shift hasn’t exactly been intuitive for me. Funny enough, we’re expected to pivot constantly on the job, by learning new stacks and new systems; when it comes to our own careers, that same adaptability can be hard to find. But here’s the thing: problem-solving is what we do. So if you’re out there grinding, wondering if it’s still possible, know that I think it is. Rethink your strategy. Build proof. Connect with people who are learning and sharing too. It’s not easy work, but it beats sending 1,000 applications into the void. You’ve got this. 👊  ( 7 min )

It is well known that software development is a lifelong learning process. At the start of my career, most of my early interactions involved SQL databases. I used many SQL administrative tools, such as DBeaver, SQLiteStudio, and MySQL Workbench. When I first began working with DynamoDB, I didn’t realise early enough that I needed a mindset shift, and I am sure quite a few developers fell into a similar trap. In designing my DynamoDB table structure, I treated queries and access patterns as afterthoughts and focused more on mappings and relationships between items and entities, just as I would with a relational database. Persistently applying these old SQL habits often led me to deal with inefficient scans, which was deeply frustrating. When working with DynamoDB, you need to shift your min…  ( 9 min )

This is a story about how simple precautionary measures can save you hours of work and a fair bit of your sanity. At MobilityData, we created the MobilityDatabase to host public transit and shared mobility feeds. Our infrastructure lives in Google Cloud Platform (GCP), and everything is deployed using Infrastructure as Code (IaC) powered by Hashicorp Terraform. In theory, Terraform keeps everything tidy and predictable. In practice... well, let's just say Murphy's Law also lives in the cloud. At a high level, Terraform revolves around three main ingredients: Configuration files (.tf): These define what your infrastructure should look like, which services to create, their properties, and dependencies.

Hey everyone!!! Tihar is here in Nepal 🎉. With the holiday break on, I decided to wrap up another portfolio project: designing and deploying a complete, event-driven e-commerce order processing system on AWS. I’ve previously built a few monolithic REST APIs, but this time I wanted to challenge myself and understand how microservices differ from monolithic systems in practice. So I chose a microservices architecture centered around an Event Bus (Amazon EventBridge). While the project follows a microservices pattern, my main goal wasn’t to build a fancy UI or user-facing backend — instead, I focused on AWS architecture, infrastructure, and operational maturity. To push myself deeper into the IaC world, I decided to deploy everything using raw CloudFormation YAML — no SAM, no CDK, no Terr…  ( 10 min )

Tutorial about metrics which are used for machine learning model validations. The metrics covered in this tutorial are balanced accuracy, precision, recall and F1-score. This same tutorial may be read in a portuguese version here. During a data science project one of the most wished steps is the development of a machine learning model. In this step there's training and validation of the model, and one of the most used metrics to validate the machine learning model is accuracy. However, how far can the accuracy show how effective the model was in classifying two or more classes? Therefore, in this post other metrics will be described. They will help you to get other perspectives on the performance of your model, especially with unbalanced databases, in other words, databases with more numbe…  ( 10 min )

In the current landscape of artificial intelligence, the discourse is often a confusing mix of world-changing hype and technical jargon.

Changing Password Supabase provides a built-in functionality for resetting passwords via a link. However, if you want to change your password while logged in, there is no built-in functionality for this scenario. To handle this, you can use a custom function on Supabase. Run the following code in your Supabase SQL Editor: create or replace function changepassword("current_plain_password" text, "new_plain_password" text, "current_id" uuid) returns varchar language plpgsql security definer as $$ DECLARE encpass auth.users.encrypted_password%type; BEGIN SELECT encrypted_password FROM auth.users INTO encpass WHERE id = current_id and encrypted_password = crypt(current_plain_password, auth.users.encrypted_password); -- Check the currect password and update IF NOT FOUND THEN return 'incorrect'; else UPDATE auth.users SET encrypted_password = crypt(new_plain_password, gen_salt('bf')) WHERE id = current_id; return 'success'; END IF; END; $$ This will create a custom function that you can call from any platform. Here’s the syntax for Javascript: const { data, error } = await supabase.rpc('changepassword', { current_plain_password: oldPassword, new_plain_password: newPassword, current_id: currentUserId }); Here- current_plain_password is the old password new_plain_password is the new password current_id is the id in the current session of the app. Logging Out from Active Sessions on Other Browsers/Devices To sign out from all active sessions, you can use the following commands: // defaults to the global scope await supabase.auth.signOut() // sign out from the current session only await supabase.auth.signOut({ scope: 'local' }) // sign out from the other session without the current await supabase.auth.signOut({ scope: 'others' }) Upon sign out, all refresh tokens and potentially other database objects related to the affected sessions are destroyed and the client library removes the session stored in the local storage medium.  ( 7 min )

When working with React Router v6, I found myself wishing for a feature that doesn’t exist — parallel routes. That’s why I built parallel-router 💡 The Problem React Router v6 is amazing, but it doesn’t natively support rendering two distinct route outlets at once. ⚙️ The Solution parallel-router introduces a wrapper that allows multiple route contexts to exist side by side: This makes it super easy to create layouts like: Chat apps (list + conversation) Dashboards (menu + content) Multi-view editors 📦 Try it out: 🔗 NPM: https://www.npmjs.com/package/parallel-router 🔗 Docs & Demo: https://salekin02.github.io/parallel-router 🔗 GitHub: https://github.com/salekin02/parallel-router 🧠 What’s next I’m planning to extend support for other versions of React Router and would love your feedback on what features you’d like to see next!

DevOps is more than a role; it's a culture and mindset that bridges the gap between development and operations. Any member of an IT organization or software company can embrace DevOps principles to improve collaboration, streamline processes, and enhance software delivery. Any person can carry more than one role. However, the literature for DevOps often starts with operations: system administrators, infrastructure engineers, and site reliability engineers (SREs). One of the best books on the topic, The Phoenix Project, is written from the perspective of an operations manager (and I highly recommend reading it). DevOps is about operations, but it is also about development. In truth, DevOps is about the entire software lifecycle and thus any person involved in it can learn and grow into a De…  ( 12 min )

Escolher entre uma arquitetura monolítica e uma arquitetura de microsserviços é uma das decisões mais importantes no desenvolvimento de software.

I have wanted to write about tech conferences for a while, and last week I was at Codemotion in Milan. Perfect excuse to finally do it. If you follow me here you know I usually share tutorials and technical content, but there is another huge part of our craft that I discovered only a few years ago: conferences. They open new opportunities and new ways of thinking that you will miss if you only focus on the tech. That would be a shame.

Recently, our People & Culture team shared something in our Learning Nuggets Slack channel: “The Four Tendencies” quiz, a framework by Gretchen Rubin that explores how people respond to expectations. The premise is straightforward: we all face external expectations (from others) and internal expectations (from ourselves). The way we respond to these defines which of the four tendencies we belong to: “I do what others expect of me—and what I expect from myself.” They meet both outer and inner expectations with discipline and consistency. Their motto: “Discipline is my freedom.” “I do what I have to do. I don’t want to let others down, but I may let myself down.” They readily meet outer expectations but struggle with self-imposed ones. “I do what I think is best, according to my judgment.

We gave an AI Coding Assistant a design file. Here is what happened. AI is changing everything - including how we build software. Coding assistants are everywhere, and the hype is real. But so are the concerns: Will it scale? Can I trust the output? What happens when things go wrong? We get it. We are a software company ourselves and like everyone else: we are under pressure to deliver more, faster and smarter. So we asked us a simple question: what if we could make AI coding assistants "safe by design"? In our product, architecture and design are not an afterthoughts. They are executable assets packaged as living design files that define: what gets built, how it works and why it matters. So we took a coding assistant - in this case, the choice fell on Cursor - to run a hackathon. We didn’t write user stories. We didn’t hand over vague requirements. Instead, we fed the coding assistant the structured design artifacts generated from the knowis Workbench. Simple. The Result? It worked well: Code generation was fast, focused, and aligned with our intent. Architecture guardrails stayed intact, even with rapid iterations. Review and testing? Easier than ever. Shifting the (investment) focus to the "left" of the software development process doesn’t just mean testing earlier. It means thinking, designing earlier. Better. Because AI accelerates code but architecture and design defines what gets built. In a few words: you don’t need to fear coding assistants. You need to feed them better inputs.

My two kids are quite different. The younger one is our chatterbox while the older one barely shares a thing. "How was school? Fine." At 'circle time' in school, every kid is supposed to go around sharing one thing that makes their heart happy. My kid has 'passed' every.single.time. for over a year! Needless to say, this has been a delicate balance in our household of trying to get more but not be pushy about it so we create a safe space. Well, we had a breakthrough over the weekend! We hosted friends for a few nights and got to witness one of their family rituals - "highs and lows". Every night, this family shares one high and one low they experienced during the day. Usually done over dinner but if they can't all be present, right before bed time. I think one of the keys is that everyone is involved. Level the playing field. They invited us to do it with them one night and I was sure my kid would pass as she scrambled to hide behind my partner and look away from everyone waiting for a response. To my utter shock, she participated! Enthusiastically. My partner and I were shocked, and decided this was something we would need to try again. And we have, and it's worked! She will thoughtfully reflect on her day and pull out something that made her happy, and something she was less than pleased about. It's not a super long conversation but it feels special that it's coming honestly from her as opposed to a response to some sort of interrogation by us. I'm hoping this can be a new daily routine...forever? If we can bake it in as just how our family functions, I hope we can hold it through the teenage years and beyond. Anyway, just wanted to share! I know there are a million tricks out there so this is just one of many you could try if you have a quiet kid too.  ( 8 min )

Header — περιγράφει τον αλγόριθμο υπογραφής και το τύπο, π.χ. { "alg": "HS256", "typ": "JWT" }. 2. Payload — JSON με claims (π.χ. sub, exp, iat, roles, custom claims). Αυτό το κομμάτι — το “Payload” μέσα στο JWT — είναι ουσιαστικά η καρδιά του token, εκεί που αποθηκεύονται οι πληροφορίες (claims) για τον χρήστη ή τη συνεδρία. Το payload είναι ένα JSON αντικείμενο με key–value ζεύγη, που πε…  ( 12 min )

What if you could give your WordPress members access to exclusive content — and automatically remove it after a few days? Now imagine doing this without passwords, logins, or subscriptions — just by using a digital token or NFT. That’s what time-limited token gating brings to WordPress. “Token gating” means giving access to something (like a post, page, or video) only to people who hold a specific digital token in their wallet. key — if you have the key, you can enter. For example: An artist sells 100 NFTs — only NFT holders can view the “members-only” gallery page. A course creator rewards early supporters with lifetime access using a special token. A club offers entry to NFT holders instead of printed cards or passwords. It’s like a membership system — but powered by the blockchain. He…  ( 7 min )

Có bao giờ bạn cảm giác lạc lõng, chông chênh, mất định hướng trong công việc? Chào các bạn, Hiện tôi đang là Senior Frontend Engineer cho một công ty trong lĩnh vực y tế.

Sí, he encontrado el lenguaje de programación perfecto. Ni C# ni Python, que son los que he estado empleando hasta este momento, son capaces de cubrir mis necesidades como puede hacerlo GulfOfMexico. Merece la pena echarle un vistazo. ¿Booleanos true/false? Eso es demasiado limitante. Los booleanos pueden tener tres valores: true, false y maybe. Hay verdaderas constantes. ¡Solo márcalas insistentemente con const! Por cierto, sí, el final de instrucción es la exclamación ('!'). const const const pi = 3.14! ¿Listas que empiezan en 0 (como C), o en 1 (como en Basic)? ¡Mejor en -1! Por cierto... ¡Por fin! ...puedes acceder a posiciones con números reales, en coma flotante. const var scores = [3, 2, 5]! scores[0.5] = 4! // 3, 2, 4, 5 Los operadores past y previous permiten consultar el pasado... y el futuro. const var score = 5! score++! print(score)! //6 print(previous score)! //5 print(next score)! //7 ¿Tu código solo fluye de arriba a abajo? ¡Estás obsoleto! Déjame presentarte la instrucción reverse. Buena parte de esta flexibilidad es la posibilidad de sobrecargar variables. const const message = "Hello"! print(message)! const const message = "world"! reverse! Además, hay que tener en cuenta que la palabra clave function cuenta con todos los alias resultantes de eliminar letras (en orden) de esta palabra clave: fi bonacci (n) => { const var sum = 1! const var i = 0! when (i < n) { sum += sum + previous sum! i++! } } Por no mencionar el operador delete, que permite eliminar aquellos elementos que nos estorben. delete null! // El error del millón de dólares delete 13! print(12 + 1)! // Error! ¿A qué esperas? ¡Adelante, instálalo y disfrútalo! Eso sí, ten en cuenta que es necesario instalarlo a través de su instalador. A su vez, el instalador debe instalarse mediante el instalador del instalador.  ( 7 min )

In the first post of this series, Building an AI Scoring Agent: Step-By-Step, I described the technical details of building an AI Scoring Agent for scoring open-ended science questions. This post analyzes the behavior of the prototype tool, and reflects on appropriate and inappropriate use cases for a tools like this. TLDR: This shouldn't be used for scoring tests or exams!!! As a recap, the tool takes in a scoring guide, a question, and a student response, and outputs a score and an explanation for the score. The sections below analyze the behavior of the agent when it is working as expected, as well as analyzes its workflow and output when things go awry. In many cases, the agent works as expected, following a predictable workflow as described in the code and summarized in the first post…  ( 13 min )

LLMs as Data Mines: Unearthing Gold from 'Thought' Circuits Ever felt like you're drowning in data, but still struggling to find the right examples to train your AI? You're not alone. Feeding your large language model (LLM) the perfect diet is key to unlocking its full potential, but sifting through mountains of information is a real bottleneck. What if the LLM itself held the secret to curating that ideal dataset? The core idea is simple: LLMs, when tackling complex tasks like math problems, activate specific, interconnected groups of 'neurons' – think of them as dedicated 'thinking' circuits. We can measure how strongly different data points activate these critical circuits within the LLM. The data that lights up these circuits the most intensely is, unsurprisingly, the most relevant a…  ( 7 min )

These past couple of weeks we've been improving our existing feature spec suite to prepare it for switching over to --headless=new chrome option. click_button "Update" expect(record.reload.field).to eq("new value") oftentimes failed because the button click hadn't been fully processed yet, so click_button "Update" expect(page).to have_flash_message("Update successful") expect(record.reload.field).to eq("new value") Another source of deeper fragility was the behavior of .set and fill_in - sometimes, especially if an input already had a value, the new value would either be appended or not inputted at all. We significanly reduced the incidence of these fails by specifying a clear option like this: config.before(:each, :js) do Capybara.default_set_options = { clear: :backspace } end  ( 6 min )

AI agents are becoming more powerful every day. They can chat, write code, answer questions, and help with tasks that once required human reasoning. They all share one challenge: how to handle knowledge/context over time. Two architectural patterns have emerged to fill this gap: Retrieval-Augmented Generation (RAG) and Memory. Both aim to make large language models (LLMs) more capable, context-aware, and cost-efficient. Yet they solve different problems and fit different stages of an agent’s lifecycle. In this article, we’ll explore both in simple terms, show how they differ, and explain when to use each, or both together. LLMs are stateless by design. Each prompt is processed independently; once you send a new request, the model forgets everything that happened before unless you include i…  ( 10 min )

How document-driven structure transforms stateless AI assistance into continuous, auditable engineering You're in your fifth AI session today. The code is flowing faster than you've ever experienced. Then you ask the AI to integrate yesterday's work—and it has no idea what you're talking about. This is the paradox of modern AI-assisted development: your code appears faster than ever, but your project feels more fragile. Research from GitHub, IBM, and METR documents what developers are experiencing: AI excels at generation but struggles with integration. In isolated sessions, output is fast and often high-quality. Across multiple sessions, coherence breaks down. Context vanishes. An AI might write a perfect authentication handler today, then suggest changes tomorrow that silently break it. …  ( 17 min )

Summary Lede : Enterprise systems often operate in silos, forcing users to switch contexts and applications to complete business tasks. By connecting SAP’s robust business processes with Microsoft Copilot Studio agents, organizations can now bring critical operational data and transactions directly into Microsoft 365 and Teams—where people already collaborate. This integration enables AI-driven, conversational interactions with SAP systems, eliminating the need to switch applications and accelerating decision-making and productivity across the enterprise.

I recently spent 3 hours debugging a simple config file parser. What should have been a 5-minute task turned into a nightmare of BufferedReader, try-with-resources, charset issues, error handling, and manual backup management. I realized Java's file I/O is scattered and outdated. That's why I built OpenLoom, a modern, zero-dependency Java library that unifies reading, writing, searching, and managing files efficiently. Traditional Java file I/O often looks like this: try (BufferedReader br = new BufferedReader(new FileReader(file))) { String line; while ((line = br.readLine()) != null) { if (line.contains("config=")) { // Logic buried in 20+ lines } } } catch (IOException e) { // More boilerplate } Search/Replace requires manual loops and backup…  ( 7 min )

If you’ve ever tried to move from one major version to another, you know it’s not just about running bundle update rails and calling it a day. Things break, dependencies complain, tests start failing, and suddenly what was supposed to be a “simple upgrade” becomes a sprint-long debugging marathon. That’s where being prepared can make or break your release. At RailsFactory, after helping dozens of teams navigate Rails upgrades (some smooth, some not so smooth), we realized something simple: most upgrade headaches start way before the upgrade actually begins.

C# 14 is almost here, so it's time for our annual feature overview. This year brought fewer changes than the last. Some might consider them minor, but is it really so? Let's take a closer look. Yes, we can now omit writing a field for a property. Some might say that we could already write properties like this: public string Name { get; set; } This is an auto-implemented property, which creates a hidden field. However, the problem is that it can only be used when no additional logic is required. If we need such logic, we have to create a field just to store the data so we could process it in the property setter. For example, when we need to trim whitespaces from an email address before saving it, we would typically write something like this: public class User { private string _oldEmail;…  ( 12 min )

Hey #Symfony developers and #webdev community! Are you constantly battling those frustrating Access-Control-Allow-Origin CORS errors, especially when dealing with OPTIONS preflight requests from your frontend? You're not alone! The common pitfall is that OPTIONS requests often arrive without any payload or route parameters, causing Symfony's router (and especially #[MapRequestPayload]) to fail before CORS headers can be applied. Instead of reaching for a heavy bundle, here's a professional, lightweight solution: an Event Listener. By implementing a CorsSubscriber on the KernelEvents::REQUEST event with a high priority (e.g., 9999), you can intercept all OPTIONS requests right at the start of the Symfony lifecycle. This listener can then construct an immediate HTTP 200 response, inject the necessary Access-Control-Allow-* headers, and prevent further processing (like routing or DTO mapping). This approach ensures your API sends the correct CORS signals to the browser, unblocking your frontend operations. It's a clean, performant, and framework-native way to achieve full CORS compliance. For a full code example, detailed explanation, and best practices, check out the complete guide on my site: https://agconsulting.altervista.org/symfony-cors-risolvere-errore-options/  ( 6 min )

Ever clicked through your web app on multiple browsers and noticed something looked slightly off—or worse, a feature didn’t work at all? That’s why cross-browser testing is essential. Users expect your app to work seamlessly on Chrome, Firefox, Safari, Edge, and even some legacy browsers. Any hiccup can affect user experience, trust, and ultimately your business. The good news? Open source testing tools make this process a lot easier. By automating browser tests, you can quickly spot inconsistencies and ensure your app behaves the way it should—without spending hours manually checking each browser.

Most people in IT have at least heard of assembly language. Some even saw it during university - just enough to know it exists, but not enough to use it for anything real. Assembly used to be the secret behind high-performance code. Games like Quake, graphics engines, and device drivers often had big chunks written in assembly for one simple reason: speed. But times changed. Modern developers rarely touch assembly anymore, and for good reasons. Until recently, it simply didn't make sense for most projects.

In August 2020, nearly 40% of A-level students in England saw their grades downgraded by an automated system that prioritised historical school performance over individual achievement. The algorithm, designed to standardise results during the COVID-19 pandemic, systematically penalised students from disadvantaged backgrounds whilst protecting those from elite institutions. Within days, university places evaporated and futures crumbled—all because of code that treated fairness as a statistical afterthought rather than a fundamental design principle. This wasn't an edge case or an unforeseeable glitch. It was the predictable outcome of building first and considering consequences later—a pattern that has defined artificial intelligence development since its inception. As AI systems increasing…  ( 30 min )

Risk management has evolved from a back-office function to a strategic imperative that touches every aspect of modern business operations. The regulatory landscape continues to expand and become more complex, with new laws emerging around data privacy, environmental responsibility, financial transparency, and workplace safety.

Transit Gateway (TGW) is a service that connects multiple VPCs and on premises networks using a single gateway. Before Transit Gateways if you had multiple VPCs that needed to talk to each other, you had to create multiple peering connections. Each connection required manual routing, was non-transitive and hard to scale. TGW solves this by acting as a regional layer 3 router which provides transitive connectivity between attached VPCs, centralised control over routing and propagation, and can scale to thousands of VPCs. TGW Attachments are the connections between the TGW and the VPCs or VPNs. Each attachment represents a link between a specific VPC or VPN and the Transit Gateway, allowing for efficient traffic routing. Without attachments the TGW doesn’t even know those VPCs exist. A TGW by default has one route table and all other attachments use this for table for routing decisions. Routes are propagated from the attachments. A route table can contain static routes, propagated routes automatically learned from attachments that you enabled to propagate into this table and blackhole route with “blackhole = true” to drop matching traffic and prevent specific paths. TGW makes a routing decision based on the route table associated with the ingress attachment. This means that traffic entering from Attachment A will look at A’s associated route table to decide where to send the packet next. Return traffic will look at the returner’s associated table to avoid asymmetric routing. An association binds one TGW route table to an attachment and determines which route table a connection (attachment) uses. That table governs egress from that attachment and you can re-associate an attachment to a different TGW route table at any time. Propagation lets an attachment advertise its network prefixes into a TGW route table automatically so other attachments associated with that table can reach it without manual static routes. You turn propagation on per attachment per TGW route table.  ( 7 min )

🚀 A Glimpse Into the Future of Browsing You know that feeling when technology just works — like pure magic? So, I thought, what if I asked AI to do everything for me? Talking to My Browser I opened Comet and typed this into Perplexity: “Open YouTube, find the official NASA Moon landing video and jump to the moment Armstrong says ‘one small step for man.’” All that — without me touching the keyboard again. 🤯 🌐 Why This Is So Impressive This moment really hit me. 🧩 What Makes Comet + Perplexity Special Here’s why this little experiment blew my mind: Contextual Understanding Perplexity understood what I meant, not just what I said. It identified the “official NASA Moon landing video” and ignored unrelated clips. ⚙️ Try It Yourself If you want to see how it feels to command your browser with just words: Download Comet Browser Open a new Perplexity tab and ask: “Open YouTube, find the official NASA Moon landing video, and jump to Armstrong’s first step.” Sit back and watch as it does everything automatically. You’ll understand instantly why people are calling Comet the future of human–AI interaction.  ( 9 min )

The last time I felt like a programmer, people who wrote programs called themselves that (not Devs). So, hi. A long time ago, I didn't finish my computer science training. I wanted to make software when I grew up ... but, I never did. For clarity, this was a long while ago. Some time shortly after the Millennium bug didn't end the world, but before the first internet bubble had properly burst. It was around a time when the mini-disk was the best piece of technology known to man (and, fwiw, imo, it perhaps still is). Before burning out of college in a mad few months of mostly partying, I had been on cruise control. I was well on my way to starting a career in the one thing I ever thought I was good at. It turned out I was going to have a less straightforward relationship with the tech ind…  ( 7 min )

Let's be honest: playing with large language models is amazing, but seeing that OpenAI API bill at the end of the month can be... painful. 😅 I've been working with the GPT-4 and GPT-3.5 APIs a lot, and I noticed how quickly the costs can spiral out of control. A simple task routed to GPT-4 by mistake, an inefficient prompt, or running the same query over and over—it all adds up. I kept thinking there had to be a smarter, more automated way to manage this without rewriting all my code. That's why I built CostLens, a simple SDK I'm hoping can help other developers who are facing the same problem. At its core, CostLens is a drop-in SDK that automatically helps you cut your AI costs. The goal is to make it a "set it and forget it" tool that starts saving you money in minutes. It works by wrap…  ( 7 min )

In today’s fast-moving digital landscape, your applications are the front door to your customers, your brand’s reputation, and your revenue. If an app is slow, buggy or down, you don’t just lose time; you lose trust and business. That’s why implementing strong Application Performance Monitoring (APM) is no longer optional. Application Performance Monitoring (APM) refers to the suite of tools, processes and instrumentation that track how your business applications perform, how they respond under real-user load, where bottlenecks exist, and why problems occur. Rather than waiting for users to complain or outages to happen, APM gives you visibility into the inner workings of your apps from the front-end request through back-end services, databases and external calls.

In today’s fast-paced software world, logging often gets treated as an afterthought—a few lines sprinkled here and there before a release. But when a production incident strikes at 3 AM, those logs become your North Star ✨ for making sense of chaos. After years in backend engineering and incident response, it’s clear: logging isn’t just about recording events—it’s about building observability into your system from day one. 💡 Research shows developers spend up to 35–50% of their time debugging issues. And a big chunk of that time is wasted digging through incomplete logs or trying to guess what really happened. In production, where you can’t just “add a print statement,” logs become your system’s black box 📦 Consider the real-world impact: Faster incident fixes: Teams with great logs reso…  ( 7 min )

Introduction In today’s world, almost every app you use — from Netflix to Spotify — runs on AWS (Amazon Web Services). But how does AWS actually work behind the scenes? The AWS Flow Explained The AWS architecture is built on a client-server-cloud model. Client This is where everything starts. The client can be: A web browser, A mobile app, or Any IoT device sending a request. The client sends a request (like logging in, fetching data, or uploading a file) to AWS servers. AWS Cloud Layer This is the core of the process. EC2 for computation (running servers and apps), S3 for storage, RDS for database management, Lambda for serverless execution. The AWS Cloud acts as the brain — managing scalability, security, and speed automatically. Database & Application Layer Here, the actual data and logic live: Database: Stores your user information, transactions, etc. Application Layer: Runs your backend code, APIs, or microservices. Both layers work together to process your request efficiently and securely. Network Layer Once AWS has processed everything, the results are sent back through its high-speed global network. User Finally, the user sees the response — maybe a webpage, dashboard, or streaming content — all delivered instantly thanks to the AWS global infrastructure. Why AWS Flow Matters Understanding this flow helps you design scalable and fault-tolerant systems. You can optimize how your app connects to the cloud. You learn to separate computation, storage, and networking for performance. You get a clearer idea of where services like CloudFront, Route53, or IAM fit in. Developer Takeaway AWS isn’t just hosting — it’s an entire ecosystem that powers millions of apps. AWS makes cloud computing simple — but understanding how its flow works internally gives you a professional edge. Whether you’re building a small portfolio project or an enterprise-grade app, knowing this structure helps you think like a cloud architect.  ( 7 min )

Microservices with Node.js: A Comprehensive Guide Introduction In the dynamic landscape of modern software development, the monolithic application architecture is increasingly making way for more flexible and scalable approaches. Among these, the microservices architecture has emerged as a leading solution, particularly favored for complex and evolving applications. Microservices involve breaking down a large application into a collection of small, independent, and loosely coupled services that communicate over a network. This architectural style promotes agility, resilience, and independent deployability. When paired with Node.js, a lightweight and powerful runtime environment built on Chrome's V8 JavaScript engine, developers gain a potent combination for building efficient and scalab…  ( 10 min )

App Store: link Most productivity tools push output. They want more tasks, more deadlines, more alerts. Clarity does not come from doing more. It comes from knowing what deserves attention. I like the Getting Things Done (a book about getting things done) idea of capturing everything so the mind can relax. I wanted a quieter way to do that. Mind Backlog is my take on GTD: capture, clarify, choose, and move on with less noise and more care. Think of your thoughts like a lightweight sprint board. Ideas, questions, and unsolved problems live here. Backlog is not failure. It is permission to let something rest until you are ready. Items you are tackling in this sprint. You decided they are solvable now or worth your energy today. Resolved or released. The goal is not endless checkboxes. The goal is to release mental load. You write what is on your mind. The app asks one question: Can I solve this right now? If yes, send it to What's the next Task. If not, let it rest in Backlog. Can I name the next action? If yes, send it to Active. If not, we will keep it warm in the Backlog. No due dates. No streaks. No pressure. Just a simple flow that helps you think clearly and act with intention. This is not a task grinder. It is a thought organizer. It helps you notice what is calling for attention, sort what is actionable, and let the rest breathe until you are ready. Sometimes the best productivity tool is not the one that makes you do more. It is the one that helps you think better.  ( 6 min )

The performance claims are impressive: Up to 10x faster Fast Refresh: Your changes will appear in the browser…  ( 9 min )

I’ve lost count of how many times I’ve spun up a new Express app just to test something. Then I forget the command I used, Google it, and end up watching yet another “Build a REST API in 30 Minutes” video on YouTube. Sound familiar? Express.js is the backbone of so many backend projects — from side hustles to serious production systems — but actually learning it well takes more than copy-pasting from tutorials. So, after testing a bunch of learning platforms, here’s my honest breakdown of what’s worth your time in 2025. Let’s be real: you can technically ship an API with just a couple of lines of Express. But if you want to build things that scale and impress other developers, here’s why Express is still worth learning deeply: Simplicity that scales: Minimal setup, tons of flexibil…  ( 9 min )

The Rose’s Whisper: ADC as the Listener 🥀 On his tiny planet, the Little Prince kneels by his rose, her petals trembling. “What’s wrong?” he asks, but her voice is a soft sigh—a voltage too faint for his notebook (microcontroller) to read. Then he finds a golden ear (ADC) tucked in the grass, etched with “Translate.” “Hold still,” he says, pressing the ear to her stem. The ear hums, sorting her whispers into numbers: 36.2°C—Thirsty, but brave ✨. “How?” the prince asks. The ear chuckles: “I’m a SAR ADC—like you guessing her favorite water amount: ‘Is it 10ml?’ ‘No, 5ml?’ Until I find the truth.” Nearby, a Sigma-Delta ADC (a fox-eared device) sits, patient: “I listen longer,” it says, “like the fox waiting to be tamed—hearing every quiver, even the quiet ones.” The rose smiles: “Finally, so…  ( 8 min )

Every team has that one person, or two, who insists that “frontend tests are a waste of time.” They might say E2E tests are flaky, or that QA already does the job. But deep down, skipping tests isn’t a bold time-saving move; it’s a long-term productivity trap. Here’s how to win the argument (and save your project from endless regressions). Frontend changes are deceptively simple. You tweak a component or update an API call, and suddenly the login form stops working. Having automated tests for critical flows (login, checkout...) ensures that your app’s core functionality never silently breaks. Without tests, the real testers are your users, and they’re the worst kind of testers. Fixing a bug found in production takes exponentially more time than catching it during development. Manual QA can…  ( 7 min )

While other databases out there might shard, CouchDB is one of the few that does it automatically and saves you the annoying — read error-prone — work of setting it up yourself. Being unique in this way, it’s a topic you may not know too well. The arcane-sounding term (especially if it reminds you of the prismatic variety) doesn’t need to conjure confusion or intimidation. In this post, we’re going to take a deeper look at scaling CouchDB with shards: what sharding is, plus why and how to do it. Any given central processing unit (CPU) — the thing on which your database lives — has a physical limit to how much processing it can do at one time. By extension, there’s a limit to how big your database can get if you still want to do useful things with it if it can only run on a single core. D…  ( 15 min )

In some of the previous blogs, I wrote a lot about the IoT platform from Total.js. Like what it is, why it can be useful, how to install individual parts to get it working, and how to set it up and start using it. But there is still one part of the platform that has to be created or modified especially for your case. And those are drivers. We published some of the custom drivers we used before, but now we have added universal drivers. These drivers are ready to use. We created universal drivers for the electrometer, weather, meteo data, and switch. In this blog, I will introduce them to you. You can use them as they are, create new drivers based on principles used in these drivers, or modify them for your case. Also, I will show you how to add a sensor to one of them, so you will be able t…  ( 10 min )

Introduction In general you would want to deploy infrastructure using terraform, build and push docker images in CI/CD phase. But let's say, just in case, someone pointed a gun at your head asking you to build and push docker images from within Terraform, how would you do it? Fear not, I am here, let me save you today. It's simple, we will just wait check for file change - where a specific Dockerfile is kept, if any changes are detected we will build the image and push it. You have to have aws cli configured (v2 is prefered but v1 will just do) Terraform installed (I am using 1.5.5) So this will be our directory structure - . ├── src │ └── frontend │ ├── Dockerfile │ └── index.html └── Terraform ├── ecr.tf ├── main.tf └── variables.tf Here, we have a very basi…  ( 9 min )

🧠 Lexical Scoping and Closures — Ever seen a function in JavaScript remember a variable even after it's done running? That’s not magic — it’s Lexical Scoping and Closures. Let’s break it down with real-world analogies, demos, and how the industry uses it. Lexical Scoping means: "Variables are accessible based on where they are written in the code — not where they are called." Imagine your house has rooms. If you leave your phone in the living room, you can use it there. But if you go to the kitchen, you can’t use your phone unless you bring it with you. Same with code — variables live in their scope (room). Functions can access variables in their room and the rooms outside — but not inside other rooms. function outer() { const message = "Hello from outer!"; function inner() {…  ( 7 min )

Stage 1 of the HNGi13 QA Track focused on reviewing requirement documents and translating them into an actionable test plan. For this task, I worked on Gradific, a grading and task management platform for educators. My goal was to understand how features like workspace creation, assignment setup, and grading flow together, and then design a testing strategy around them. I started by analyzing the PRD and FRD, identifying core functionalities and edge cases. From there, I created a structured Test Plan outlining objectives, scope, approach, risks, and deliverables. I also designed 10 detailed test cases to validate and verify that the requirements are met and the system works as expected. This experience taught me how important it is to plan before testing commence, understanding requirements deeply helps uncover gaps early and ensures focused, efficient testing. Key Takeaway Translating requirements strengthens both product understanding and tester intuition. HNGi13 #QA #SoftwareTesting #HNGInternship #TestPlanning #QualityAssurance #BugDetective  ( 6 min )

In today’s fast-paced business world, organizations are constantly juggling countless communications, projects, and data streams. From Slack messages to emails, meetings, and shared documents, the sheer volume of information can overwhelm even the most organized teams. Yet, the most successful organizations operate like a finely tuned organism. Their secret? A “nervous system” that connects people, information, and workflows seamlessly. In this blog, we explore how building the nervous system of your organization can transform productivity, collaboration, and decision-making. Without a nervous system: Knowledge gets siloed in private chats or individual heads Every conversation, file, and decision is captured and connected Too many tools fragment information. Teams switch between Slack, email, Trello, and Google Drive, losing time and focus. Centralizing communication into one intelligent workspace ensures that: Conversations are linked to tasks, decisions, and files Automatically extract action items from meetings and messages Step 3: Connect Teams to Expertise Match questions or problems to team members with relevant skills Step 4: Make Data Actionable Convert conversations into searchable knowledge Step 5: Foster a Culture of Transparent Communication Encourage teams to share context instead of hiding it in DMs Why Nexy is the Nervous System Your Organization Needs Capture and store every conversation, file, and decision Conclusion Address — Company Name — Nexy Location — Netherlands  ( 8 min )

Abstract We introduce the Beta-Rho Orthogonality (BRO) score, a novel metric that quantifies the consistency between systematic risk exposure (beta) and correlation in cryptocurrency markets. Unlike traditional metrics that treat beta and correlation as separate measures, the BRO score reveals structural market relationships by examining their ratio. We demonstrate that this simple formulation serves as a multi-purpose analytical tool for: (1) detecting regime stationarity, (2) identifying tradeable structural relationships, (3) classifying predictability, and (4) constructing market-neutral portfolios. Our framework reveals four distinct behavioral regimes in crypto markets and provides a quantitative basis for distinguishing between manageable volatility and unmanageable chaos.

When Kotlin was announced as an official language for Android in 2017, I didn’t rush to learn it. Java felt familiar, and I didn’t see the point in switching. Then one weekend, I tried rewriting a small project in Kotlin. Suddenly, everything was cleaner. No more endless boilerplate. Null safety built right in. Functional features that just worked. I didn’t just like Kotlin—I wanted to use it everywhere. That was my turning point. And I’ve seen the same story play out with countless devs. Kotlin starts as “the thing Android makes you use” and ends up becoming your favorite language.

I’m excited to announce that three of my UI designs were showcased during the Appian Community’s UX Design Lab | Mobile & Responsive Design livestream! 🎉 Seeing my work highlighted alongside so many creative and thoughtful submissions was an amazing experience. The session, hosted by Christine Danzi and Jennifer Higa, focused on the principles that make Appian applications not just functional — but intuitive, responsive, and user-friendly across all devices. Building for responsiveness goes beyond scaling layouts. Here are some of the core insights shared during the session that every Appian designer should keep in mind: Ensure that essential information remains visible and accessible on smaller screens without overwhelming the user. Design navigation structures that feel natural for mobile interactions — like bottom tabs or collapsible menus. Buttons, links, and interactive components should have ample spacing for easy tapping and accessibility. Use Appian’s dynamic layouts and conditional visibility to modify component behavior based on device size. Always test your designs on different screen widths to ensure consistent experiences across mobile, tablet, and desktop. Here’s a quick look at the responsive UI submissions that were featured in the livestream: A huge thanks to Christine Danzi and Jennifer Higa for hosting such an engaging session and providing valuable feedback on making Appian designs truly responsive. Events like these highlight the power of community learning — where every designer, developer, and contributor helps push the boundaries of what’s possible in low-code UX design.  ( 8 min )

Protect your web applications from automated content theft and AI data harvesting. In recent years, the rise of artificial intelligence has accelerated data collection across the internet. Many AI models rely on large-scale web scraping to feed their algorithms. Unfortunately, this often means that your website content — articles, APIs, or even private datasets — may be harvested without consent. These AI scrapers operate differently from ordinary bots. They mimic real browsers, rotate IPs from various countries, and simulate human-like behaviors to bypass traditional security tools. Some even execute JavaScript or use headless browsers such as Puppeteer or Playwright to collect dynamic content. For website owners, this raises serious concerns: Intellectual Property Theft: Your unique cont…  ( 9 min )

Whether you’re in .NET, Node.js, Java, or Python — you need to care about what hosts your app trusts. And it’s straight out of the OWASP Top 10: Let’s check both sides of “allowed hosts” In ASP.NET Core, you’ll often see this in appsettings.json: { "AllowedHosts": "example.com" } That’s not for redirects, API calls, or URLs inside your app. https://evilproxy.com, the request is dropped. Think of it as your front door lock 🏠 — 💡 Other frameworks have similar controls: Express.js → use helmet() or host-validation middleware Django → ALLOWED_HOSTS in settings.py Spring Boot → server.forward-headers-strategy with a proxy-aware filter Now comes the untold part: When users can submit or trigger URLs (for example, a redirect after login, a webhook, or an image fetch), attackers can trick yo…  ( 7 min )

Optimistic Superposition: A Quantum Leap for AI? The dream of truly intelligent AI hinges on our ability to train complex models, a process currently bottlenecked by sheer computational cost. Imagine training a model not in weeks or months, but in hours. What if we could explore solution spaces previously deemed intractable? This is where "optimistic superposition" comes in. At its core, it's a novel algorithmic approach designed to handle complex problem-solving by strategically delaying computationally intensive calculations. Instead of immediately tackling every possible scenario, the algorithm makes optimistic assumptions, carries these assumptions as constraints, and only resolves them when absolutely necessary. This "wait-and-see" approach drastically reduces the initial computati…  ( 7 min )

GitHub Home I remember a few years ago, I was leading a team to develop a real-time stock ticker dashboard. 📈 Initially, everyone's enthusiasm was incredibly high. We were all excited to build a "live" application with our own hands. But soon, we found ourselves stuck in the mud. The tech stack we chose performed reasonably well for ordinary REST APIs, but as soon as WebSockets came into the picture, everything became unrecognizable. Our codebase split into two worlds: the "main application" that handled HTTP requests, and a "separate module" that handled WebSocket connections. Sharing state between these two worlds, like a user's login information, became a nightmare. We had to resort to some very clever (or rather, ugly) methods, like using Redis or a message queue to synchronize data. …  ( 10 min )

User retention is one of the most important drivers of long-term app growth. While most teams focus on improving the product experience or adding new content to increase engagement, these changes often require long development cycles. So, is there a faster and more direct way to retain subscribers? retention campaigns come in. When executed strategically, subscription retention campaigns use timely incentives—such as discounts, exclusive access, or feature unlocks—to re-engage users who are at risk of canceling or who’ve already churned. reduce churn but also recover lost revenue and extend your app’s subscription lifecycle (LTV).

Blockchain technology has grown well beyond its origins with Bitcoin. While it started as a tool to run cryptocurrency networks, it now supports many industries by providing robust data security, transparency, and efficiency. Here is an updated look at blockchain in January 2025, covering its nature, types, key applications, and real-world examples. Blockchain is not a typical database where you can revise or remove entries. Instead, it acts like an "append-only digital log." Once data such as transactions or events goes on the chain, it becomes extremely difficult to alter. This approach delivers strong data integrity and security, but it also presents challenges related to data volume and network scalability.

Honestly, before I started this benchmark, I never imagined the performance differences would be this dramatic. As a junior computer science student, I always thought framework selection was mainly about features and ecosystem, and performance was just, well, good enough. That changed last month when our lab's project started crashing under load, and my advisor asked me to investigate which framework we should actually be using. That evening in my dorm room, setting up the test environment, my roommate laughed and said, "Are you becoming a performance engineer now?" I didn't think much of it at the time. I just figured if we're going to choose, we should choose something solid. What I discovered through testing surprised me in ways I didn't expect. Let me back up to our lab project.

Beyond Binary RAG: Enhancing Decision-Making with Nuanced Risk Assessment The all-too-familiar Red, Amber, Green (RAG) system has become a staple in risk management and decision-making processes across various industries. However, an over-reliance on this binary approach can lead to oversimplification of complex issues, resulting in inadequate risk assessment and suboptimal decision-making. The Problem with Binary RAG The traditional RAG system categorizes risks into three distinct states: Red: High-risk or critical situations that require immediate attention. Green: Low-risk or stable situations that require minimal attention. Amber: Medium-risk or uncertain situations that require monitoring. While this system provides a basic framework for risk assessment, it often fails to capture the nuances of complex issues. The binary nature of RAG can lead to: False negatives: Critical risks being overlooked due to their classification as Amber. **... This post was originally shared as an AI/ML insight.

Many challenges in AI products stem less from choosing frameworks and more from how user experience (UX) and architecture shape each other. I first noticed this while using ChatGPT to draft and maintain product requirement documents (PRDs) — reusing prompt variants, manually curating context, and constantly tweaking outputs to stay aligned. The workflow technically worked, but it felt brittle and overly manual.

Presented by Arm A simpler software stack is the key to portable, scalable AI across cloud and edge. AI is now powering real-world applications, yet fragmented software stacks are holding it back. Developers routinely rebuild the same models for different hardware targets, losing time to glue code instead of shipping features. The good news is that a shift is underway. Unified toolchains and optimized libraries are making it possible to deploy models across platforms without compromising performance. Yet one critical hurdle remains: software complexity. Disparate tools, hardware-specific optimizations, and layered tech stacks continue to bottleneck progress. To unlock the next wave of AI innovation, the industry must pivot decisively away from siloed development and toward streamlined, e…

Or a chaotic pile of Notifiable, Taggable, SoftDeletable, and ThatThingWeNeededForTheMarketingReport? This folder is more than just a directory; it's a Rorschach test for your application's architecture.

This week, I implemented a new feature for our beekeeping management platform 🐝: deduct the sold amount from the batch table and record the sale in a separate sold_honey table — atomically.

For the longest time, I kinda felt like a fraud. I'd browse LinkedIn, Threads, Instagram, X, Dev.to and all sorts and see posts like "I built a full-stack AI app in a weekend!" I'd listen to colleagues talk about their elaborate side projects. The unspoken message was clear: a real developer codes for fun. A real developer is always learning the next thing, always building. And I... wasn't. After eight hours of solving problems, writing code, and staring at a screen, the last thing I wanted to do was more of the same. I'd force myself sometimes, opening my laptop with a sense of dread, only to produce low-quality code and feel even worse. I thought this meant I wasn't "passionate" enough. I thought I was falling behind. Then, I hit a wall. I was stuck on a gnarly backend problem for days. …  ( 8 min )

In this project, we explored model evaluation metrics using a Lead Scoring dataset. The goal was to identify which factors most influence lead conversion and evaluate how well our model can predict them. Below are the key concepts and lessons learned throughout the assignment. A lead scoring model helps businesses identify which leads (potential customers) are most likely to convert. By assigning a score to each lead, sales teams can focus their efforts where it matters most — improving conversion rates and efficiency. In our dataset, the target variable (converted) indicates whether a lead converted (1) or not (0). The features included data such as: lead_score number_of_courses_viewed interaction_count annual_income Before modeling, we performed crucial preprocessing steps: Handling Miss…  ( 7 min )

Every great application begins with a simple, honest object. It does its job, it tells the truth, and it asks for little in return. It’s the UserService that fetches data, the Image that renders itself, the API that returns a response. But as our systems grow from humble scripts to sprawling architectures, this honesty becomes a liability. A naïve UserService can buckle under a million requests. A direct Image load can freeze a UI. A raw API call can be a gaping security hole. We need a guardian. A diplomat. An illusionist. We need the Proxy Pattern. This isn't just another Gang of Four entry.

I thought about the scene, described it carefully, and then had some help from AI when implementing it. Finally, I converted it to HAML, which is really convienient when using codepen.  ( 6 min )

I just finished my first complete machine learning project—a renewable energy investment analysis dashboard that's now live on Streamlit Cloud. Three days of work. 181,915 rows of data. And one really important lesson: your initial business problem is probably wrong. I'm a software engineer learning ML with Claude designing my course. This project clarified a lot about how data science work actually happens. I started with a plan: build a tool to help optimize fossil fuel plant modernization schedules based on renewable production patterns. Sounded reasonable. Turned out to be impossible with my data. I had a renewable energy dataset covering 52 countries from 2010-2022. Six energy types. Good coverage. But after loading it into the interactive EDA dashboard I'd built the previous week, re…  ( 10 min )

Author: Samantha Laine King Last Updated: October 2025 This guide walks through adding a clean, accessible Dark Mode toggle to a React application using Tailwind CSS and localStorage. It covers setup, theme persistence, and best practices for accessibility. Tailwind provides built-in dark mode support. In your tailwind.config.js file, enable class mode so users can manually toggle it: // tailwind.config.js export default { darkMode: 'class', theme: { extend: {}, }, plugins: [], } This allows you to switch themes by adding or removing the dark class on the root element. We’ll use a custom React hook to manage theme state and persist it in localStorage. // useDarkMode.ts import { useEffect, useState } from 'react' export default function useDarkMode() { const [theme, set…  ( 7 min )

Automata Alchemists: Transmuting Reinforcement Learning into State Machines Tired of hand-coding complex state machines? Imagine a world where your machine learning model automatically infers and implements them! What if we could leverage AI to build AI? The future of program synthesis might be closer than you think. Think of a reinforcement learning agent exploring an environment, learning optimal actions to maximize a reward. We can repurpose that learned behavior to define the state transitions of an automaton. Instead of rewarding specific actions, we reward reaching desired states or completing specific sequences of actions. The result is an automated process to build Finite State Machines that execute deterministic sequences. We essentially train an AI to become a DFA. The agent ex…  ( 7 min )

Your MCP server works perfectly. Python tests all green. You deploy to staging, connect Claude Desktop, and immediately hit this error: Input validation error: '[16]' is not valid under any of the given schemas You try different formats. Arrays, integers, strings. All fail. Same cryptic message every time. I spent two hours debugging this evening. Turns out there's a mismatch between how FastMCP's Python client handles optional parameters and what Claude Desktop sends over the wire. I was building an MCP server for a RAG system.

One of the things I love about Go is how practical it is when dealing with JSON. The encoding/json package provides two main ways to work with JSON: - In-memory (Marshal/Unmarshal) - Stream-based (Encoder/Decoder) Let’s break it down. 1. Marshal and Unmarshal — for small or simple data These are the most common functions when your JSON fits comfortably in memory. ▶️ Go → JSON (Marshal) You convert a Go struct, map, or slice into JSON. type User struct { Name string `json:"name"` Email string `json:"email"` } user := User{"Hugo", "hugo@example.com"} data, err := json.Marshal(user) if err != nil { log.Fatal(err) } fmt.Println(string(data)) Output: {"name":"Hugo","email":"hugo@example.com"} Use Marshal when: You already have a Go object in memory.

Hey everyone, If you're a developer, you've probably been in this situation: a client sends you a database_dump.sql file, or you need to set up a local copy of a production database for testing. The usual process is tedious: Install the correct database server (Postgres? MySQL?) Create a new user and database Figure out the right command-line flags to import the .sql file Hope there are no version conflicts It's a frustrating 15-minute detour from the work you actually want to do. I got tired of this workflow, so I built a solution right into my app, FormPipeDB. It's a feature that allows you to take an entire SQL script—CREATE TABLE statements, INSERT INTO statements, and all—and turn it into a live, fully manageable database just by pasting it into a textbox. Here's how it works: Click "Import SQL..." Paste your entire SQL script. Click "Import Database." That's it. The app parses the script, creates all the tables, defines schemas, populates the data, and even builds foreign key relationships for you. You go from a static .sql file to a fully interactive database you can edit and query visually in less than a minute. This has been a game-changer for my workflow, especially for: Faster Prototyping: Instantly spin up a backend from an existing schema. Easy Debugging: Quickly load a snapshot of production data to test against. Client Work: Set up a database for a client project without any server configuration. The app is called FormPipeDB. I'm on a mission to get my first 100 paid users, so I'm running a $99 lifetime deal. I'd love for the dev.to community to check it out and give me honest feedback. You can try it at formpipedb.com.

Starting Out — and Feeling Lost I started my full stack software engineering career right out of college as a bright-eyed, bushy-tailed computer science graduate with terrible impostor syndrome. Who can relate? Between the firehose of onboarding information, a brand-new work environment, and an unfamiliar schedule, I felt completely overwhelmed. IBM ran large cohort-based onboarding workshops, and on top of that, I was meeting with different members of the team to learn as much as possible before jumping into real work. When the time came to tackle my first ticket, I was clueless. I needed to implement a privacy auditing feature across the stack — which, at the time, used vanilla JavaScript on the front end, Node.js on the back end, and IBM DB2 for the database. The codebase was relative…  ( 8 min )

Today, I decided to challenge myself with a small C++ project. Being a junior developer, I wanted something that matches my level but still pushes me to learn. I followed tutorials from ProgrammingAdvices.com, but I didn’t just copy — I experimented, debugged, and tried to write clean code in my own way. At first, I got stuck many times, but each mistake taught me something new. ⚙️ Here’s a source code of my project: View source code This small project reminded me that every step counts, and even tiny projects can teach a lot.

Funções AWS Lambda são opções extremamente práticas que simplificam todo o processo de disponibilização de aplicações serverless. Um desses maus costumes é a exposição de chaves de API externas ou conexões de banco de dados diretamente dentro do corpo de uma função Lambda. São incontáveis as vezes em que encontrei códigos semelhantes ao mostrado abaixo: Nem é preciso dizer o quão ruim é manter suas configurações assim! Essa exposição de chaves é extremamente prejudicial por alguns fatores, dentre eles: Vulnerabilidade da aplicação: qualquer vazamento de código, seja em um repositório público ou por um ataque, expõe suas credenciais ao mundo externo; Falta de escalabilidade: caso seja necessário trocar de conexão com a base ou atualizar um par de API Keys, será preciso publicar novamente o…  ( 7 min )

A technical deep dive into storage packing, tiered detection, and mathematical optimization As blockchain developers, we constantly face a trade off: security versus cost. More security checks mean higher gas costs. But what if I told you we achieved both 40% gas savings AND mathematically proven security?

The Realization I was working with Claude on some gnarly legacy code when it hit me: I’ve been vibe coding long before anyone called it that. You probably know what vibe coding is, even if you’ve never heard the term. It’s often pinned on junior devs who use AI to write code they barely understand—but real vibe coding is something else entirely. It’s what experienced developers do when we glance at a block of code and just know if it’ll work. We skim Stack Overflow, yank in half-understood libraries, and adapt stranger-solutions to weirdly specific problems. To new devs, it looks like wizardry. To us, it’s Tuesday. And here's the kicker: everyone treats AI-assisted coding like uncharted territory, as if we're all stumbling into the future hand-in-hand. But we’ve been collaborating with “…  ( 11 min )

Light Casters: So lets maek some different light sources, different types of light behave differently. Some lightsources are super far away but super bright whilst some are close but weaker. Directional Light: With this in mind theres no reason to calculate how each fragment compares the the light source position, since they are all coming from the same place essentially. So lets remove that from our light struct and change the lightDir calculations accordingly. And this should be the result. (Dont forget to set a direction for the light struct either!) Point Light: Faking fading light looks kind of fake without the proper mathematical equation, point lights tend to shine bright at a close position but quickly fall of as you get slightly further away, less of a gradual fade and more of…  ( 8 min )

When AWS experienced a global outage, it disrupted more than cloud services — it disrupted learning. As an ALX AWS Cloud Architect observer, I watched how the outage impacted Vocareum labs and brought cloud resilience principles to life. Here’s what it taught us about designing for failure, recovery, and real-world reliability. On October 20th, 2025, something strange happened — AWS went dark. At first, it felt like a typical hiccup. But soon, messages started pouring in across the ALX Cloud Architect community: “My Vocareum lab won’t load.” It wasn’t just one of us. It was everyone. The Ripple Effect The outage didn’t just stall projects — it became a live case study. Students running hands-on labs couldn’t deploy instances, monitor workloads, or test automation pipelines. For many, it was frustrating. For others, it was a wake-up call about the fragility of even the biggest systems we rely on. And that’s when it hit me: this is what cloud architecture is really about. Lessons Reinforced From the chaos came clarity. Every principle I’d studied in my ALX Cloud Architect track suddenly had real weight: High Availability isn’t just a term — it’s your safety net. Multi-Region Design matters because failures do happen. Monitoring and Alerts aren’t optional — they’re your early warning system. Fault Tolerance isn’t about preventing crashes; it’s about recovering fast when they happen. It was one of those moments where the theory became alive. The Way Forward After the dust settled, I found myself more inspired than frustrated. If AWS — the gold standard of reliability — can stumble, it only proves that no system is perfect. As cloud professionals in training, our mission isn’t to eliminate outages. And maybe next time an outage strikes, we’ll be the ones explaining why it happened — and how to prevent it from taking everything down.  ( 7 min )

It's relatively simple these days to spin up an OpenTelemetry demo and / or auto-instrument services with OpenTelemetry. That's fine - when it works - but it's when something breaks that perhaps you realise you don't quite understand what's going on under the covers. I've lost count of the number of times customers have reported "broken traces" to me as they flow through an uninstrumented tier, a load balancer or a queue. In the following video I show precisely how distributed tracing using OpenTelemetry is able to do what it does (for HTTP) by spinning up two Python FastAPI applications, instrumenting them using OpenTelemetry and demonstrating that the traces are "broken" in Jaeger. Then I solve the issue (hint: it's all about propagation). The code for all of this can be found here: https://github.com/agardnerIT/python-fastapi-requests-traceparent  ( 6 min )

As a developer, you’ve probably encountered various MySQL errors while working with databases. One common issue that can be quite frustrating is the ERROR 1130 (HY000): Host '192.168.7.7' is not allowed to connect to this MySQL server. This error typically occurs when trying to connect to a MySQL server from a remote machine using tools like TablePlus or MySQL Workbench. In this post, I’ll walk you through the steps to troubleshoot and resolve this connection error, so you can get back to developing without any interruptions. Let’s dive in! Understanding the ERROR 1130 The error ERROR 1130 (HY000): Host '192.168.7.7' is not allowed to connect to this MySQL server occurs when your MySQL server rejects connections from a remote host (in this case, 192.168.7.7).

You’ve spent weeks architecting the perfect AI agent. You’ve fine-tuned your prompts, selected a powerful Large Language Model (LLM), and are ready to connect it to the outside world. But then you hit the wall. One tool needs a REST API call structured this way, your database requires a different protocol, and your local file system feels a world away. Every new capability means another bespoke, brittle integration. You’re not building a streamlined agent; you’re managing a chaotic switchboard of incompatible plugs and sockets. This fragmentation is the silent friction slowing down the development of genuinely powerful, multi-talented AI systems. What if there was a universal standard, a common language for LLMs to talk to tools, data, and services? Enter the Model Context Protocol (MCP). …  ( 12 min )

Memory leaks are a common issue in Node.js applications, especially when running inside containerized environments like Kubernetes. A memory leak occurs when an application keeps allocating memory without releasing it, leading to increased memory usage and eventually to container restarts or crashes. Here’s a typical graph of what a memory leak looks like: memory usage constantly increasing over time until the pod is restarted. Unclosed Redis or database connections Global variables accumulating data Event listeners that are never removed In short: memory leaks happen more often than you think, especially in complex services. And the tricky part? You won’t always see them in your local environment, since production traffic and timeouts behave differently. In our case, for example, the lea…  ( 8 min )

React Component GPT: We need a GPT that understands our React components, knows our CSS variables, and can spit out code that's ready to use. This isn't about general knowledge; it's about our knowledge. The standard GPT knowledge upload is fine for broad docs, but for precise component generation, we need control. That's where Actions come in. Our design system lives in zeroheight. Our CSS variables are in a .css file. Our React components are in .jsx files. These are all discrete sources of truth. A generic LLM has no idea how they connect. If someone asks for a "primary button," it might give generic HTML, not our Button component with --color-brand-primary. Unacceptable. We build an API. This API becomes our "knowledge retrieval service." The GPT uses Actions to call this API when it…  ( 7 min )

When I started building my own startup, I had one goal — to turn ideas into something real fast enough to test if people even cared. That’s the truth most founders learn the hard way: it’s not about building a perfect product, it’s about learning fast and adapting even faster. In 2025, speed is everything. The tools are smarter, AI is everywhere, and customers expect products to work right out of the gate. But despite all that, the fundamentals haven’t changed — execution, clarity, and discipline still win. Here’s what I’ve learned while building and launching MVPs (Minimum Viable Products) for startups and for my own company, EulerHive.

How we evolved from Git chaos to a workflow that actually works for agency client projects "Which branch has the latest changes?" It was 4 PM on a Friday, and we had a client demo scheduled for Monday. Three developers had been working on different features, and nobody was quite sure which branch contained what. We had feature/new-dashboard, client-feedback-updates, johns-branch, fix-urgent-bug, and staging all containing different versions of the codebase. Merging everything took the entire weekend. The demo Monday morning included two features the client had specifically asked us not to include yet, was missing one they'd approved, and had a critical bug we thought we'd fixed in a different branch.

Yesterday, the internet had a bad day — and so did millions of users and businesses around the world. On October 20, 2025, Amazon Web Services (AWS) experienced a major outage that disrupted everything from streaming platforms and smart homes to enterprise apps and financial services. This wasn’t just another technical hiccup. It was a stark reminder of how fragile the modern internet can be when so much of it depends on a handful of companies. The issue began in the US-EAST-1 region — AWS’s most popular and densely used zone.

Among those affected were McDonald’s, Apple Music, Microsoft 365, Al…  ( 7 min )

I want to share with you a powerful AWS serverless pattern that uses two of my favourite AWS services: AppSync Events and EventBridge Pipes.

Il giornalismo trattato come scienza comincia dalla definizione delle variabili: evento, contesto, attori, effetti. Senza un lessico condiviso, il racconto diventa aneddoto. Il taccuino è un laboratorio portatile: si formulano ipotesi, si cercano confutazioni, si annotano incertezze con la stessa dignità dei fatti accertati. Il campionamento delle fonti segue criteri espliciti: indipendenza, prossimità ai dati primari, competenza. Una testimonianza singola pesa come un indizio, non come una prova. La regola è triangolare: documento, voce diretta, osservazione sul campo. Quando due elementi concordano e uno diverge, si indaga il perché del disallineamento. La misurazione non è solo numeri. Anche le parole hanno metriche: frequenza, coerenza temporale, compatibilità causale. Le citazioni si trattano come segnali: si eliminano i “rumori” (opinioni non verificate, interessi nascosti), si puliscono i bias, si indicano i margini d’errore. Un buon pezzo espone non solo cosa si sa, ma quanto e con quale confidenza. L’etica è il protocollo di sicurezza. Proteggere le fonti equivale a proteggere l’apparato sperimentale: senza fiducia, i dati non arrivano. La proporzionalità guida ogni scelta: mostrare un nome, un volto, un dettaglio privato richiede di dimostrare l’utilità pubblica superiore al danno possibile. La trasparenza metodologica è parte del risultato. La pubblicazione chiude il ciclo e apre il successivo. Rendere disponibili i materiali, linkare gli archivi, spiegare passo per passo come si è arrivati alle conclusioni permette la replicazione da parte della comunità. Così il giornalismo non si limita a “informare”: costruisce una base cumulativa su cui altri possono testare, correggere e avanzare.  ( 6 min )

Introduction: The Hidden Cost of Poor Incident Follow-Up How did this happen again? Didn't we prepare for this? No engineering leader wants this message—especially after months of careful planning.

Senior executives had to spend days personally reassuring frustrated customers, promising once again to finally address the underlying issues.

Imagine this — you create a beautiful piece of software on your system. It runs perfectly, fast and smooth. But the moment someone else tries to run it on their machine, it breaks. One system says “library not found”, another says “version mismatch”. The software worked fine in your world, but not in theirs. This was the never-ending loop of frustration every developer once faced. In the early stages of software development, everything lived directly on the physical computer. Each machine had its own setup — operating system, installed software, dependency versions. That meant if you deployed the same code on ten different servers, it could behave ten different ways. To tackle this inconsistency, Virtual Machines (VMs) were introduced. A Virtual Machine acted like a computer inside another…  ( 8 min )

Introduction In my previous article, I introduced the FHIR Data Explorer, a proof-of-concept application that connects InterSystems IRIS, Python, and Ollama to enable semantic search and visualization over healthcare data in FHIR format, a project currently participating in the InterSystems External Language Contest. In this follow-up, we’ll see how I integrated Ollama for generating patient history summaries directly from structured FHIR data stored in IRIS, using lightweight local language models (LLMs) such as Llama 3.2:1B or Gemma 2:2B. The goal was to build a completely local AI pipeline that can extract, format, and narrate patient histories while keeping data private and under full control. All patient data used in this demo comes from FHIR bundles, which were parsed and loaded into…  ( 9 min )

Every programmer has encountered it — that one phrase whispered with a mix of fear, awe, and exhaustion: “That part of the code is… legacy.” Legacy code — the mysterious beast that has survived through years of updates, countless developers, missing documentation, and still powers your company’s core systems. It’s both a curse and a miracle that it still runs. The “crap” part defines its internal quality (or lack thereof): Logic tangled like spaghetti: Hundreds or even thousands of lines in a single function, seven layers of if-else, and mysterious conditions that even the original author no longer understands. Random naming conventions: Variables like a1, temp2, dataList3, and functions called handle() or processData(). You read the name and still have no clue what it does. No comm…  ( 8 min )

Ever been worried about bots scraping your data, attackers brute-forcing logins, or your platform getting hit with a sudden spike in expensive operations? Without proper protection, a simple DDoS attack or bot script can cost you time, resources, and even thousands in third-party service fees (like SMS). Let me show you how to implement a thread-safe, high-performance rate limiter using Python, FastAPI, and Redis. Rate Limiting: Allow only X requests per Y seconds per user. For example: 100 requests per 60 seconds Fast: Stores data in memory, allowing for near-instantaneous read/write operations critical for low-latency APIs. Automatic Windowing: The EXPIRE command lets us define a "time window" (e.g., 60 seconds) after which the counter is automatically cleared, saving manual cleanup code…  ( 7 min )

In this tutorial, we'll walk through the creation of a simple physics-based doll using the Pixalo game engine. We will cover each part of the code step by step, explaining its purpose and functionality. 1. Importing Pixalo First, we need to import the Pixalo engine into our project. This can be done through a CDN link. Here's how we do it: import Pixalo from 'https://cdn.jsdelivr.net/gh/pixalo/pixalo@master/dist/pixalo.esm.js'; Next, we'll create a new instance of the Pixalo engine and set up our game canvas. We define the dimensions and background color, as well as the physics properties (in this case, gravity). const game = new Pixalo('#canvas', { width: window.innerWidth, height: window.innerHeight, background: '#031C1B', physics: { gravity: { y: 800 } } …  ( 9 min )

Why Cursor over Claude Code? Code-generation diffs are easier to review and roll back (the checkout system is great). You can test and use other models for different tasks (o3 for complex tasks, gemini-2.5-pro for creativity, grok-code-fast-1 for quick tasks, etc.).* Good IDE integration (e.g., accept/reject actions work great across the UI). *That said, I’m only using claude-4.5-sonnet since its launch. Use .cursorrules or similar to enforce behavior. For example: - Always use the project’s Tailwind colors. - Always use named exports with object parameters: `sum({ a, b })` instead of `sum(a, b)`. - Use "pnpm" instead of "npm" for all package-management commands. - Use the "use client" directive when using client-side state like useState, useEffect, etc. - Don’t modify package.json dep…  ( 7 min )

The cloud promised to simplify everything — agility, lower costs, and effortless global deployments in just minutes. But… what about security? Securing cloud environments has become far more complex than most expected, while opening a door for attackers is easier than ever. By its very nature, the cloud allows both employees and cybercriminals to access systems from anywhere in the world — as long as they have the right credentials and no additional controls are in place to stop them. This accessibility, one of the model’s greatest strengths, is also its Achilles’ heel. In this article, we’ll debunk some of the most dangerous myths about cloud security. The cloud isn’t exactly new — it’s been around for nearly 20 years (if we count from the launch of AWS). Yet, several myths continue to sh…  ( 7 min )

After a few comfortable years in the same flat, I found myself back in the nightmare that is the German housing market. Hundreds of applicants for one place, five-minute viewings, and forms that look like they were faxed straight from 1998. The worst part wasn’t even the competition - it was the Mieterselbstauskunft. It's a form that most landlords want. And you're gonna need it multiple times, thats just the housing market here. After hours of searching, it seems that there is just no real good way to fill it. To combat it, I built a small iOS app that lets you fill out and sign your rental self-disclosure digitally. Native form inputs, built-in signature with a handwriting-look, and a clean final PDF you can reuse in seconds. I know that developing it cost 20 times more time than I will save by using it. But if a handful of people start using it too, it will be a net positiv on the human-time bottom-line. If you’re curious, the app’s here: https://selbo-app.de/  ( 6 min )

Fine-Tuning LLMs: Avoiding Catastrophic Forgetting with a "Warm-Up" Approach When adapting pre-trained Large Language Models (LLMs) to specific tasks, a common challenge arises: catastrophic forgetting. This phenomenon occurs when the model's performance on the original task suffers significantly after fine-tuning on a new task. To mitigate this issue, we recommend using a "warm-up" approach with smaller learning rates. Why "Warm-Up"? The "warm-up" phase involves gradually increasing the learning rate from an initial small value to a larger one. This approach helps the model to: Stabilize the pre-trained weights: By starting with a small learning rate, you prevent the model from making drastic changes to its pre-trained weights, which are essential for its original performance. Adapt to the new task: As the learning rate increases, the model can learn to incorporate new knowledge without forgetting its original capabilities. Prevent overfitting: The ...

Model Overinterpretation: A Hidden Pitfall in XAI In the pursuit of transparency and accountability in AI decision-making, Explainable Artificial Intelligence (XAI) techniques have become increasingly popular. Methods like SHAP (SHapley Additive exPlanations) values and LIME (Local Interpretable Model-agnostic Explanations) provide valuable insights into an AI model's decisions by attributing importance to individual features. However, a common pitfall lies in overinterpreting these results, which can lead to oversimplification and misrepresentation of complex interactions between features. When using SHAP values or LIME, it's essential to remember that these methods: Simplify complex relationships: By focusing on individual feature contributions, these methods might overlook intricate dependencies between features.

Let’s be honest: how much of your day is spent re-typing the same long commands? How often do you run one command just to find an ID, then copy-paste it into the next one? Every docker ps | grep my-app, kubectl get pods -n prod, or manual copy-paste is a small interruption that kills your momentum and pulls you out of the zone. What if your shell could anticipate your next step? What if it could turn those multi-command workflows into a single, interactive action?

Agents are the New Developer 80% of Claude Code was written by AI. More than a quarter of all new code at Google was generated by AI one year ago. It’s safe to say that in the next 12 months, the majority of all new code will be written by AI. Agents don’t behave like humans. They behave in new ways. Software development tools need to evolve. Agents need a new kind of database made for how they work. But what would a database for agents look like? At Tiger, we’ve obsessed over databases for the past 10 years.

JVM - (Java Virtual Machine). Java Virtual Machine is the foundation of Java programming language and ensures the program's Java source code will be platform-agnostic. It's used to run Java bytecode. JVM is included in both JDK and JRE, and Java programs won't run without it. JVM is responsible for converting bytecode to machine-specific code(binary) and is necessary in both JDK and JRE. It is platform-dependent and performs many functions, including memory management and security. TheJVM is platform-dependent, meaning a specific JVM implementation exists for each operating system (e.g., Windows, macOS, Linux). JDK - (Java Development Kit) Java Development Kit is a software development environment that includes JRE and development tools. It's used to create Java applications and applets. JDK includes tools like a compiler, debugger, and documentation generator. JDK contains all the tools that are required to compile, debug, and run a program developed using the Java platform. These development tools include the Java compiler (javac), debugger, Javadoc tool, and other utilities necessary for writing, compiling, and debugging Java programs. JDK is essential for Java developers who need to create and compile Java code. JRE - (Java Runtime Environment) Java Runtime Environment is a set of software tools that provides a runtime environment for running other software. It's used to run Java applications. JRE contains class libraries, supporting files, and the JVM. The JRE is designed for users who only need to run Java applications and do not require development tools. For example, we write a code called first. First.java(our code) --> First.class (byte code) --> Binary code. In single line Example: JVM: is the engine that executes Java bytecode, ensuring platform independence. JRE: is the environment required to run Java applications, containing the JVM and necessary libraries.

GitHub Home I still vividly remember that Friday midnight. I, a man in my forties who should have been at home enjoying the weekend, was instead in a cold server room, the hum of fans buzzing in my ears, and a stream of error logs scrolling endlessly on the terminal before me. What was supposed to be a "simple" version update had turned into a disaster. The service wouldn't start, the rollback script failed, and on the other end of the phone was the furious roar of a client. At that moment, staring at the screen, I had only one thought: "There has to be a better way." We old-timers grew up in an era when the term "maintenance window" was a fact of life.

Web3 was supposed to be a revolution. A decentralized web, owned by its users, powered by transparency, trust, and autonomy. The vision was beautiful: an internet where middlemen disappear, creators earn directly, and users regain control of their data and digital lives. But behind the idealism lies a harder truth. Web3 is not free. It comes with hidden costs that affect developers, designers, users, and the ecosystem as a whole. Let’s unpack the real price of building the future. ⚙️ 1.

I’d tweak flags, forget exact arguments, or copy–paste broken snippets. I wanted something tiny, fast, and mine: a way to name the commands I use most and run them from anywhere with muscle‑memory simplicity. That’s how mcl — My Command Line — was born. The “aha” moment came after repeating the same flows across projects. I didn’t want another framework. I wanted a thin layer over the shell where I could: Describe commands once Reuse them with arguments and variables Keep them organized across projects See what I have at a glance With mcl you write small JSON recipes. For example: { "scripts": …  ( 7 min )

If you've worked across multiple languages or frameworks, you've probably noticed that naming conventions are everywhere, and they're not always consistent. Each project uses something different. camelCase, another prefers snake_case, and suddenly you're context-switching between PascalCase components and kebab-case CSS classes. This is a quick reference I keep handy when I'm switching projects or reviewing code. It covers the most common naming conventions, where they're typically used, and why. It's nothing fancy; it's a cheat sheet that saves me from second-guessing myself when I'm deep in the work.

A few weeks ago, I decided to take my React.js learning seriously. I had gone through tutorials, built small components, and experimented with hooks — but I wanted something real, something that could represent me as a developer. That’s when I decided: I’m going to build my own portfolio website. At first, it felt overwhelming. How should I structure the components? How do I manage state efficiently? What about responsive design? Each challenge felt like a mini-battle. 😅 As I started building: Components and Reusability: Breaking the UI into smaller, reusable parts made the code cleaner and easier to maintain. State & Props: Handling data flow taught me the nuances of React, and how small mistakes can ripple through the app. UI & Responsiveness: Making the portfolio look good on different devices pushed me to improve my CSS and layout skills. Debugging & Patience: There were moments I got stuck for hours on useEffect and conditional rendering — but solving them gave me huge satisfaction. By the end, I had a portfolio that wasn’t just a collection of projects — it was a reflection of my growth, persistence, and learning journey. 💡 Key Takeaways: Building something personal teaches more than tutorials ever can. Mistakes aren’t failures — they’re lessons in disguise. Seeing your ideas come to life is incredibly motivating. Next, I plan to connect this React portfolio with a Django backend, making it dynamic and interactive. 🔗 Check it out: https://thiyagu26v.github.io/myreactportfolio/ https://github.com/thiyagu26v/myreactportfolio ReactJS #FrontendDevelopment #WebDevelopment #Portfolio #LearningJourney #FullStackDeveloper #Django #DeveloperLife #LearningByDoing  ( 6 min )

I'm on quite a few different Discord servers, and one of them has a 3D printing channel with a catalog of STLs. Initially, it was just a bunch of posts in a specific channel that got pinned. The problem? Those pinned posts were constantly outdated and needed manual updates from moderators or whoever originally posted them. Pretty tedious and annoying to keep bugging them. One of the community members had a brilliant idea: why not use Raindrop.io? We could make it a collaborative catalog that willing contributors could help maintain. It worked great! The catalog grew into something really useful... but there was one catch. Every time someone wanted to search for an STL file, they had to leave Discord and open Raindrop in their browser.

It's been encouraging to see my browser extension, Bookmark Dashboard, has now reached 700+ users (500+ on Chrome, 200+ on Edge). Recently I have made a bunch of optimizations, and today I want to share how I implemented the drag-and-drop feature for bookmarks. Usually the browser's native bookmark manager already supports dragging and dropping bookmarks or folders to move them around. However, this convenient feature was missing in Bookmark Dashboard until now. Previously, moving bookmarks or folders mainly involved opening a modal, selecting the target location, and finally clicking a confirmation button.

Als je wel eens een 3D-design hebt gemaakt, herken je dit vast: je ontwerpt iets zorgvuldig, print het uit... en ontdekt dan dat het toch niet helemaal past of er niet uitziet zoals je had verwacht. Vaak kom je daar pas achter na de eerste of tweede print, wat natuurlijk tijd en materiaal kost. Ik liep tegen precies hetzelfde probleem aan. Daarom heb ik een simpel programma geschreven dat een live camerabeeld combineert met een .stl-bestand, zodat je met Augmented Reality direct kunt zien hoe je ontwerp in de echte wereld staat. Zo voorkom je onnodige prints en krijg je sneller een goed beeld van het eindresultaat.

It is my personal take on the subject. I hope some will find it interesting. Disclaimer: I use Node.js as an example of a JavaScript runtime in this article.

TL;DR Before writing a single line of code, take one day to model your data. This simple discipline turns chaos into clarity, prevents endless refactors, and keeps your logic aligned with real business needs. Modeling isn’t bureaucracy — it’s efficient laziness: thinking once, well, so you never have to redo the same work. Before diving in, a quick nod to a great post I read recently: These 5 Coding Habits Separate a Good Developer from a Great One. It starts with a truth I fully agree with: great developers think “why” before “how.” That mindset is exactly what this story is about — modeling before coding. There are two types of developers: those who open their editor and create tables as needs arise, and those who first pull out paper and pencil. I belong to the second category. Not …  ( 11 min )

This is the story of "SaaSify," my journey from a simple idea to a complete, sellable product on Gumroad. Chapter 1: The Idea and Design My design process started with research on sites like Lapa Ninja and Awwwards.

The Problem with Modern Framework Overhead Most modern web frameworks ship with Virtual DOM implementations that add significant bundle size before you write a single line of application code. For small to medium-sized web applications, this overhead often feels unnecessary. After working on multiple projects and consistently running into this issue, I decided to explore an alternative approach. Rynex is a zero-configuration TypeScript framework for building reactive web applications without Virtual DOM. Instead of maintaining a virtual representation and performing diff operations, Rynex uses direct DOM manipulation combined with proxy-based reactivity to achieve fast, efficient updates. The core principle is simple: when state changes, Rynex updates only the affected DOM nodes directly…  ( 8 min )

Introduction to Bert : Part One Have you ever wondered how Siri understands your voice, or how Google Translate can switch between English and Spanish in seconds? Behind these everyday miracles lies the fascinating field of Natural Language Processing (NLP) — the bridge between human language and machines. In this post, we’ll explore how NLP evolved, why it was challenging, and how BERT (Bidirectional Encoder Representations from Transformers) changed the game forever. In simple terms, NLP means teaching computers to understand and generate human language — just like how we talk or write. Think of NLP as giving machines the ability to “read” and “respond” like a human. Everyday examples: Siri or Alexa understanding our voice commands. Google Translate converting English to Spanish.

On July 26, 2025, SendGrid ended its free plan. Instead of paying $20 per month to SendGrid, I built a SendGrid alternative called WhautoMail. It connects to your own AWS SES or Mailgun account, plugs into Stripe and Chargebee events, and costs only $1 per month. No vendor lock-in. No surprise upgrades. When SendGrid killed the free plan they gave only two choices: Upgrade to $20 per month Move to another provider and rewrite all integrations As a bootstrapped founder, both options were bad. And this is common with VC-backed email tools. They offer big free tiers to acquire users, and once you are integrated and dependent, they change pricing or kill free plans. This is not accidental. This is the business model. The real problem is not SendGrid. The problem is vendor lock-in. I bui…  ( 7 min )

1. What is a Router: A router in backend frameworks (like Express.js) defines how your app responds to client requests (GET, POST, PUT, DELETE) on specific URLs. Example concept: Client → /api/users Purpose: Organizes endpoints. A controller contains the logic for handling requests. Purpose: Keep logic separate from routes. Router file defines the endpoint: router.get('/users', getAllUsers); Controller file defines the function: const getAllUsers = (req, res) => { // logic to get users }; When /users is requested, router calls the controller. project/ │ ├── routes/ │ └── userRoutes.js │ ├── controllers/ │ └── userController.js │ userRoutes.js import express from 'express'; import { getAllUsers, createUser } from '../controllers/userController.js'; const router = express.Router(); router.get('/', getAllUsers); router.post('/', createUser); export default router; userController.js export const getAllUsers = (req, res) => { try { res.status(200).json({ message: "Users fetched successfully" }); } catch (error) { res.status(500).json({ message: "Error fetching users" }); } }; app.js import express from 'express'; import userRoutes from './routes/userRoutes.js'; const app = express(); app.use(express.json()); app.use('/api/users', userRoutes); app.listen(3000); Console Logging Log req.body, req.params, req.query to verify data. Example: console.log("User ID:", req.params.id); Use Debuggers VS Code: Add breakpoints in controller files. Run app in debug mode (node --inspect app.js). Error Middleware app.use((err, req, res, next) => { console.error("Error:", err.message); res.status(500).json({ message: "Something went wrong" }); }); Test Routes Use Postman or Thunder Client. Install CORS: npm install cors Use it: import cors from 'cors'; app.use(cors());  ( 7 min )

Introduction In my previous post, we went through the not-so-glamorous part: building LLVM from source and running a pass with opt. With that groundwork out of the way, it’s time to move on to the fun part which is writing the passes. In this post, we’ll start with a bit of theory on LLVM passes, just enough to give you solid footing, and then jump straight into code. Our first real pass will be a simple one: counting the number of add instructions across an IR module. Since we’ll be working directly with LLVM IR, I’m assuming you’re at least somewhat familiar with reading it. If not, I recommend taking a little time to get comfortable reading IR first because it will make your LLVM adventure much smoother. If I had to pick two pillars of LLVM, they would be the Intermediate Representati…  ( 12 min )

How many times have I forgotten to update my localization JSON file when I added a new key? I wanted to search for something that can give me more safety when I add a new key to the localization files. My first idea was to write a node script to check all JSON files in the locales dir, but then I found this useful plugin: 18n-Check Yes, I know: It doesn't have a lot of stars on GitHub, but I tried it and it works perfectly. Why do we have to recreate the wheel? Let's dive into this plugin. You can see all the documentation inside the Readme file on the GitHub repo. here to install the plugin I used the pnpm command pnpm add --save-dev @lingual/i18n-check Then we have to create a command in package.json like this: "i18n:check": "npx i18n-check --locales public/locales -s en -f i18next && i18n-check --locales public/locales -s it -f i18next" here I'm calling i18n-check with --locales option. With this you define which folder or multiple folders you want to run the i18n checks against. My structure files are this: . └── public/ └── locales/ ├── it/ │ ├── pricing.json │ └── external.json └── en/ ├── pricing.json └── external.json I used the && operator because i18n-check wants a target to compare the files from to start. In my case, I want to have every file notify me about missing keys or invalid translations. So if you use husky precommit you can configure that with this command: pnpm run i18n:check if you try to remove any keys from any files and launch the command you can see this: So with this, every change (add or remove) in the JSON localization file will be notified, and we have to update it. Thanks for the reading. See ya ✨  ( 7 min )

In a hospital in Detroit, an AI system flags a patient for aggressive intervention based on facial recognition data. In Silicon Valley, engineers rush to deploy untested language models to beat Chinese competitors to market. In Brussels, regulators watch American tech giants operate under rules their own companies cannot match. These scenes, playing out across the globe today, offer a glimpse into the immediate stakes of America's emerging AI strategy—one that treats regulation as the enemy of innovation and positions deregulation as the path to technological supremacy. As the current administration prepares to reshape existing AI oversight frameworks, the question is no longer whether artificial intelligence will reshape society, but whether America's regulatory approach will enhance or u…  ( 22 min )

Context and Goal This task involved creating a simple API endpoint (/me) in any language and framework of choice so opted to using the Gin framework in Go. The critical requirement was that the API's response payload needed to include fresh data fetched from an external, third-party service Cat Fact Why have I chosen Go? I'm currently learning Go and this serves as an opportunity to make it a project based learning. The important architectural choice I faced was how to protect the third-party API from me. If my service goes viral(laughs) and gets 1,000 requests per second, I cannot afford to forward 1,000 requests to catfact.ninja. This would certainly cause me to be blocked. Hence, I resorted to limiting outgoing traffic by implementing a Token Bucket using golang's rate package to strictly control the flow leaving my service (strict 0.5 requests per second). If a request attempts to call the external API but the bucket is empty, we return a 429 Too Many Requests to the client, protecting the external service from my own overload. It seems I've successfully built an API endpoint that is not only functional but is also resilient (with Timeouts), reliable (with UTC timestamps), and architecturally sound (with proper traffic control). Also, I hope I have not bitten more than I can chew by joining the rigorous HNG Internship while learning a new language.  ( 6 min )

Urban life is noisy, fast, and often tiring—but it doesn’t have to be hostile. If you care about building better neighborhoods (as a resident, developer, or city official), you already know that walkability is a powerful lever for healthier, safer, more prosperous communities. In this guide, I’ll share a practical playbook for turning that principle into action—on the street, in code, and at city hall. In practice, that means learning to read the city through data, design, and daily routines, and yes, using tools like Walk Score profiles as a starting compass rather than the final word. Cities that invite people to walk do more than reduce traffic: they increase casual encounters, stimulate local businesses, and boost public health. When sidewalks feel safe and interesting, people choose t…  ( 10 min )

Data often hides intricate webs of relationships between multiple factors. In a world increasingly driven by analytics and machine learning, understanding how these factors interact is essential. Path analysis provides a powerful way to explore these connections. Imagine you want to predict the mileage of a car based on its attributes—such as horsepower, engine capacity, and number of cylinders. A simple linear regression might analyze the effect of one variable (say horsepower) on mileage. However, real life isn’t that simple. These variables interact; for instance, horsepower itself may depend on engine capacity or cylinder count. This is where path analysis becomes invaluable. It extends multiple regression by allowing complex interdependent relationships between variables. The Origins …  ( 9 min )

Intro When you need to monitor your resources with a CloudWatch alarm, what you normally have to do is to create an alarm with a specific matric of that resource. Although this gives a granular level of monitoring into your resources, you always have to add or remove alarms as and when you have new resources or when you remove a specific resource. Which is an operational overhead although it can be automated if you are using infrastructure as code tool. Another option available is to use aggregated metrics in your alarms such as CPUUtilization for EC2 so you have coverage, but at high level into a group of resources you need to monitor. The downside of this is that it lacks granular visibility into your individual resources. Also, there is only a limited number of resources that support …  ( 9 min )

Il giornalismo come scienza parte da una premessa semplice: i fatti sono ipotesi da verificare con metodi pubblici. Un titolo non è una verità, è un punto di partenza. La raccolta delle prove — documenti, dati, testimonianze, osservazioni sul campo — segue protocolli di tracciabilità: chi ha detto cosa, quando, con quali interessi e quali limiti. La verificabilità è il suo criterio di demarcazione. Come in laboratorio, si cercano fonti indipendenti e ripetibilità dell’informazione: la stessa affermazione deve poter essere controllata da altri. Le versioni alternative sono considerate “ipotesi concorrenti” e vengono testate finché non restano soltanto le spiegazioni più robuste. La metodologia giornalistica integra strumenti quantitativi e qualitativi. Dalle banche dati ai registri pubblici, dall’analisi di rete al fact-checking manuale, fino alle interviste in profondità: triangolare metodi riduce l’errore e illumina le zone d’ombra. Anche il dubbio è un dato: si dichiara, non si nasconde. L’etica funziona come normativa interna della ricerca. Trasparenza sugli eventuali conflitti di interesse, tutela delle fonti, proporzionalità tra interesse pubblico e danno potenziale: queste non sono “buone maniere”, ma condizioni epistemiche per produrre conoscenza affidabile. Senza etica, il risultato è contaminato. Infine, la divulgazione. Un buon articolo rende replicabile l’indagine: cita documenti, spiega il metodo, mostra i limiti. La forma non è solo estetica ma parte del contenuto: chiarezza, contesto e precisione permettono alla comunità di validare, confutare o estendere il lavoro. Così il giornalismo diventa un sapere cumulativo.  ( 6 min )

Week 10 – Auto Scaling, Serverless, and Databases Week 10 Like seriously—Week 10 already! 💃 I’m counting down because this journey hasn’t been easy, but I’m so grateful for my coursemates and the facilitator (Akeem Oyebanji). They make learning smoother and fun. Before you know it, it’ll be break time and then closing for the day. So cool! Today at Restart, we dove into Auto Scaling—trying to understand how it works and how to troubleshoot it. We got a surprise visit from the CTO of CIL Academy, Blessing U. Even though he could only stay for about 30 minutes, it was wonderful having him with us. Lately, we’ve been doing a lot of debugging. It’s not just about theory anymore. Debugging helps us truly understand the concepts. Each issue we fix adds another layer of learning. Today at Restart, we started learning about serverless architecture. We explored how to use AWS Lambda to subscribe to an SNS topic. It was exciting to see how serverless makes automation easier. For today, our focus was on AWS Step Functions and how they simplify workflows by connecting multiple services together. It’s amazing how AWS tools make complex processes so seamless. Today at Restart, we talked about databases. In my Week 7 article, I wrote about this topic, but this time we went deeper—learning about services like Amazon Aurora and Redshift. We also discussed database migration using AWS DMS (Database Migration Service) and how to choose the right service for different needs. This week felt like the bridge between what we’ve learned and how it all connects. From auto scaling to serverless and databases, everything is starting to click. Debugging has become part of my daily routine, and honestly, that’s how understanding truly grows.

WTF is this: Full-Stack Development with Rust Ah, the elusive dream of building anything you want, without needing a team of experts in different programming languages. Sounds like a myth, right? Well, welcome to the world of Full-Stack Development with Rust, where this dream might just become a reality. But, what does it all mean? Let's break it down. "Full-stack" refers to the ability to develop both the front-end (what users see and interact with) and the back-end (the behind-the-scenes logic and database) of a web application. Traditionally, this requires knowledge of multiple programming languages, like JavaScript for the front-end and Python or Ruby for the back-end.

In this post, we’ll explore how to combine Angular’s Signals with Dependency Injection to create predictable, reactive, and reusable component state. A Signal is a reactive value that notifies dependents when it changes. Example: import { signal } from '@angular/core'; const count = signal(0); count(); // 0 count.set(1); Managing State via Dependency Injection Create a StateService that holds signals. Provide it at the component or root level. @Injectable({ providedIn: 'root' }) export class CounterState { count = signal(0); increment() { this.count.update(c => c + 1); } } Scoped State with Component Providers @Component({ selector: 'app-parrent', providers: [CounterState], templateUrl: './parent.html' }) export class ParentComponent { state = inject(CounterState); } Using the State in child Components @Component({ selector: 'app-child', template: ` + Count: {{ state.count() }} ` }) export class ChildComponent { state = inject(CounterState); } Best Practices Keep services pure and focused on state logic. Avoid too much global state. Use computed for derived state. Prefer DI scoping over manual signal creation in many components. A complete example is here Conclusion The main benefits: Reactive updates with zero boilerplate Clean state isolation using DI Easier debugging and reasoning Next steps: Try integrating Signals in existing projects Explore computed() and effect() for advanced patterns Happy coding! I hope you found it helpful. Thanks for reading! Medium: https://medium.com/@nhannguyenuri/ Dev: https://dev.to/nhannguyenuri/ Linkedin: https://www.linkedin.com/in/nhannguyenuri/  ( 8 min )

DeepSeek-OCR represents a major advance in AI technology, offering 10x token compression for document processing. This innovation could transform how AI handles memory and context, potentially reducing the need for traditional methods like RAG. Let's break down what this means and why it matters for AI systems. DeepSeek-OCR converts documents into compressed visual representations. It achieves this by transforming text into 2D grids, using a compression module that shrinks data without losing key details. For example, a 1024x1024 image might use only 256 tokens instead of thousands. This approach keeps about 97% accuracy at 10x compression. In practice, it processes documents more efficiently than rivals, handling high volumes on a single GPU. Key specs include support for various resoluti…  ( 7 min )

Cryptography: The Hidden Engine Powering Web3 The internet is changing fast. Web3 is the newest version of the web that promises more control for users and less power for big companies. But how does it work? The answer lies in cryptography, a type of secret code that keeps everything safe and trustworthy. Cryptography is all about turning information into secret messages. It helps protect data, make sure it’s not changed, and prove that things really come from who they say they do. In Web2, companies control your data and trust is based on them. Web3 changes that by using math and secret codes so you don’t have to rely on anyone else. This means you can own your digital identity, money, and information securely. Here are some simple ways cryptography powers Web3: Keys That Unlock Your Ac…  ( 7 min )

Introduction When React executes operations like filter() and map() every time, const value = useMemo(() => { return heavyCalculation(); }, [dependency]); What the above code means "Recalculate only when dependencies change, Example: Optimizing filter processing const filteredSpots = useMemo(() => { return spots.filter((spot) => { if (filters.wifi && !spot.wifi) return false; if (filters.power && !spot.power) return false; return true; }); }, [spots, filters]); What the above code means Re-execute only when spots and filters change Do not recalculate when other state changes, such as clicking a pin Prevent unnecessary filter() calls for faster performance Summary useMemo is a hook that "remembers the calculation result." Recalculate only when the value written inside [] changes. Used to optimize heavy processing (filter, sort, reduce).  ( 6 min )

JavaScript looks simple — until it isn’t. Here are 10 JavaScript concepts that often fool even experienced developers 👇 == does type coercion, while === doesn’t. 💡 Lesson: always use === unless you enjoy debugging existential crises. this depends on how a function is called, not where it’s written. 💡 Lesson: use arrow functions or .bind() when passing methods around. Closures happen anytime a function “remembers” variables from its parent scope. 💡 Closures power things like React hooks, private variables, and debounce functions. var is function-scoped, not block-scoped — and gets hoisted to the top. 💡 Use let and const — they save you from strange timeline bugs. Functions get hoisted too — but only declarations, not expressions. It’s just a queue system. setTimeout(fn, 0) doesn’t run immediately — it goes to the queue. 💡 JS runs synchronously first, async tasks wait their turn. Even if they look identical: 💡 Two separate objects never share the same reference. Yes. It’s a 25-year-old bug that’s now part of the spec. 💡 Don’t trust typeof blindly. Use strict checks when needed. 💡 Always give fallback values if you’re not sure about array/object shapes. 💡 It’s the only value in JS that’s not equal to itself. JavaScript keeps you humble — just when you think you’ve mastered it, it throws something weird your way. Keep experimenting, stay curious, and you’ll never stop leveling up as a developer.  ( 7 min )

Did you know you can send multiple HTTP requests in parallel in Laravel, instead of one after another? That’s what Http::pool() does. It’s built on top of Guzzle and can massively boost performance when fetching data from several APIs at once. 🧠 The idea Normally, you might do this: $response1 = Http::get('https://api.example.com/users'); $response2 = Http::get('https://api.example.com/posts'); $response3 = Http::get('https://api.example.com/comments'); Each waits for the previous one. With Http::pool(), Laravel runs them all at once — so the total time ≈ the longest single request (around 1 second here). 🧩 Example use Illuminate\Support\Facades\Http; $responses = Http::pool(fn ($pool) => [ $pool->as('users')->get('https://api.example.com/users'), $pool->as('posts')->get('https://api.example.com/posts'), $pool->as('comments')->get('https://api.example.com/comments'), ]); $users = $responses['users']; $posts = $responses['posts']; $comments = $responses['comments']; $usersData = $users->json(); ⚙️ How it works The pool() method accepts a closure. Inside, you define multiple requests. Laravel runs them concurrently using Guzzle promises. Returns an array of responses (each is a standard Response instance). 🧩 Dynamic example $urls = [ 'https://api.example.com/products/1', 'https://api.example.com/products/2', 'https://api.example.com/products/3', ]; $responses = Http::pool(fn ($pool) => collect($urls)->map(fn($url) => $pool->get($url))->all() ); foreach ($responses as $response) { dump($response->json()); } 🛠 When to use it ✅ Fetch data from multiple APIs simultaneously 📚 Laravel Docs 💬 Have you used Http::pool()before?

"Understanding Scope in JavaScript —" In JavaScript, scope defines where a variable is accessible within your code. Think of it as the visibility zone for your variables. There are three main types of scope in JavaScript: global, function, and block. If a variable is declared outside of any function or block, it lives in the global scope and can be accessed anywhere in your code. const siteName = "DevBlog"; console.log(siteName); // ✅ accessible everywhere When a variable is declared with var inside a function, it has function scope, meaning it only exists within that function. function greet() { var message = "Hello"; console.log(message); // ✅ accessible here } console.log(message); // ❌ ReferenceError If a variable is declared using let or const inside curly braces { } — like in an if statement or a for loop — it has block scope and is only accessible inside that block. if (true) { let count = 5; const status = "active"; } console.log(count); // ❌ ReferenceError A common pitfall in JavaScript is the var trap. Variables declared with var are function-scoped and do not respect block boundaries, which can lead to unexpected behavior. for (var i = 0; i < 3; i++) { // do something } console.log(i); // ✅ 3 (leaked outside loop) Using let or const fixes this issue because they are block-scoped: for (let i = 0; i < 3; i++) { // do something } console.log(i); // ❌ ReferenceError To write clean and bug-free code, follow these best practices: Prefer let and const over var. Use const when a variable shouldn’t change. Keep variable scope as narrow as possible. Avoid polluting the global scope. Understanding how scope works helps prevent naming conflicts and keeps your code predictable. It’s one of those core concepts that, once mastered, makes debugging and refactoring much smoother. 🧠 Master scope → Debug less → Code smarter.  ( 7 min )

Introduction In today’s fast-paced world of web development, many developers focus on speed — shipping features as quickly as possible. But speed without structure often leads to technical debt and fragile systems. I’m Sain Bux, Full Stack Developer at TechMatter, and my approach to software engineering has been heavily influenced by research. By applying research-based methods — what I call evidence-based engineering — I’ve learned to make development decisions that are not just fast, but data-driven, scalable, and sustainable.

What these terms actually mean Common Language Runtime (CLR) Managed Code Unmanaged Code Interoperability (Interop) The Common Language Runtime (CLR) is basically the core engine of the .NET environment. It takes care of memory management, threading, code security checks, compilation, and execution — plus a bunch of system-level services like automatic memory management, security boundaries, type safety, and just-in-time (JIT) compilation. All these features are built right into the managed code that runs on top of the CLR. In other words, your C# program doesn't run directly on the operating system — it runs on the CLR. Managed code is code that runs under the supervision of the CLR. It can be written in any .NET supported language — C#, F#, VB, and so on. When you compile your source cod…  ( 7 min )

Writing code is one thing—but writing clean, readable, and maintainable code is another. Clean code not only makes your programs easier to understand but also saves time and reduces bugs in the long run. Whether you’re a beginner or an experienced developer, following clean code practices is essential. Meaningful Naming Variable, function, and class names should clearly describe their purpose. Avoid vague names like x or temp unless in a very short scope. For example: a = 10 max_user_attempts = 10 Clear names make your code self-documenting, reducing the need for extra comments. Keep Functions Small and Focused A function should do one thing, and do it well. Large functions are hard to read, test, and maintain. For instance: def process_data(data): def clean_data(data): def analyze_data(…  ( 7 min )

Over the past few months I have invested some time to contribute to an open source project I find fascinating: wasmCloud.

The Spark: My First DevFest @ IUEA Then, @DeniseAllela took the stage. Her voice cut through the noise with a clear, powerful message: "AI isn't replacing developers—it's empowering them." It wasn't about being obsolete; it was about getting superpowers. The next hour was a blur of revelations. I watched the demo of Firebase Studio powered by Gemini 2.5, realizing full-stack AI development wasn't a future promise—it was here now. The concept of Jules, a fully autonomous coding agent, hit me like a jolt. Wait, I could spend less time debugging and more time designing? But the real game-changer was seeing the Gemini CLI in action. Watching someone automate complex operational tasks with a few simple prompts, instantly grounded by Google Search for real-time information, felt like watching magic. The tools weren't just fast; they were smart. Walking out into the Kampala afternoon, the world felt different. I wasn't just a developer anymore. I was an architect of agentic systems. My mind was buzzing with project ideas, already imagining how to integrate AI agents into the app I'd been stuck on. The takeaway wasn't just a hashtag; it was a mandate: #BuildSmarterShipFaster. DevFest didn't just give me new tools; it fundamentally changed how I saw my own potential. The future of code had arrived in Kampala, and I was ready to build it.  ( 6 min )

Vim. It was a name that inspired both awe and fear. No, I am not talking about this: I meant this: For a very, very long time, I was reluctant to use Vim. I thought it was for experts and those ultra-legend programmers of yore. If quitting Vim was supposedly enough of a meme, then actually doing anything in it would be the stuff of legends, right? Well, last year, my friend started using it. And making some cool stuff. Things like nvim, nerd-tree, tmux, neofetch, etc, made it seem like he had ascended to the next level of programmer-kind. And then he showed it to me and said: “Learn and use Vim; it is very useful and easy. It is up to you, of course, but if you don’t, then I’ll silently judge you”. Very nice friend, I agree.

Alle paar Monate liest man dieselbe Schlagzeile: „Mass Adoption steht vor der Tür.“ Doch sobald man eine typische Web3-App wirklich benutzt, wird schnell klar, warum wir noch weit davon entfernt sind. Die UX im Kryptobereich ist nach wie vor zersplittert, und genau hier können wir Entwickler ansetzen. Schon einfachste Aktionen bestehen aktuell aus zu vielen einzelnen Schritten: mehrere Wallets mehrere Chains unerwartete Gas Fees Bridges, Swaps, Signatur-Pop-ups, Approvals externe On-Ramps und Off-Ramps Für neue User ist das keine „dezentrale Freiheit“. Es ist ein Hindernisparcours aus Reibungspunkten. Was die Nutzer wirklich wollen (Spoiler: Nicht mehr Features) Sie wollen: ✅ Onboarding in einem Flow Wenn eine normale Banking-App so funktionieren würde wie ein durchschnittliches dApp-Interface, würde sie niemand benutzen. Es gibt aber positive Entwicklungen Fairerweise: Das Ökosystem macht Fortschritte. Account Abstraction setzt sich durch mehr menschenlesbare Transaktionen integrierte Fiat-On-Ramps (Dienste wie MoonPay lösen zumindest ein großes Hindernis) Wallets, die endlich UX statt nur „Power Features“ priorisieren Zum ersten Mal sehen wir Web3-Produkte, die sich wie echte Produkte anfühlen — nicht wie Prototypen. Wie Entwickler echte Adoption voranbringen können Wir sollten uns fokussieren auf: Komplexität abstrahieren (Kette verbergen, Aktion in den Vordergrund) Fehlbedienungen abfedern (Warnungen, Simulationen, Guardrails) Für Nicht-Techniker zuerst designen Die ersten 5 Minuten perfektionieren (Onboarding entscheidet alles) Die nächste Nutzerwelle wird nicht von der besten Technologie gewonnen, sondern von der reibungslosesten Nutzererfahrung.  ( 6 min )

Binding in XAML is one of the cleanest ways to keep your UI and logic in sync. You just have to know how it thinks. Once you understand how {Binding} and {x:Bind} behave under the hood, how they resolve data, when they update, and what they quietly ignore, it stops feeling like magic and starts feeling like control. These are the ten common binding pitfalls that, once you spot them, make XAML feel like the powerful, predictable system it was meant to be. Your binding path looks correct but nothing displays. The Visual Studio XAML Binding Failures window shows "Cannot resolve symbol" errors. You forgot to set DataContext on the element or any of its ancestors. Fix it by setting DataContext explicitly in code-behind or XAML, or use ElementName or Source to bypass DataContext entirely. In Win…  ( 9 min )

In modern engineering organizations, DevOps is no longer about “running deployments” — it’s about empowering developers to build, deploy, and scale safely and independently. Over the last few months, I’ve been refining a Platform Engineering playbook focused on one simple goal: 👉 Enable developers to self-serve infrastructure — securely, efficiently, and with full cost visibility. Here’s what I’ve learned along the way: 💡 Golden paths beat golden rules — instead of more docs, create reusable templates that guide developers down the right path. 🧱 Guardrails, not gates — automate compliance and security checks via policy-as-code (OPA, Kyverno, Sentinel). 💰 FinOps from day one — right-sizing defaults, TTLs for ephemeral environments, and showback dashboards prevent surprise invoices later. ⚙️ Platform = Product — maintain a roadmap, collect feedback, track adoption, and measure value (DORA, SLOs, cost savings). When done right, this shift reduces lead time by 60%, infra tickets by 70%, and cloud spend by up to 25%. But most importantly — it gives developers freedom without sacrificing control. 🔥 I’d love to hear from others in the DevOps / Platform / FinOps world: How are you approaching developer self-service and cost governance in your organization?  ( 6 min )

Creating terraform or other infrastructure as code for a new project can be daunting for some. This shows how you can easily crank out a new deployment to meet your requirements using Github copilot prompt files and a few free MCP servers. For the heck of it, we will also convert between two totally different cloud providers to deploy the same infrastructure. Github copilot is getting more powerful with each update and I've been enjoying using it quite a bit to write quick scripts and even initializing whole project repositories for me. But I've never been very impressed with it (or any other LLM's) ability to create solid terraform. I've been exploring model context protocol (MCP) servers quite a bit lately and figured perhaps they can augment an agent with enough additional capabilities …  ( 13 min )

Modern websites need to look great on all devices, and developers need layout tools that can handle complexity without chaos. While Flexbox is fantastic for one-dimensional layouts, it starts to feel limited when you need to structure both rows and columns at once. That’s where CSS Grid Layout comes in—a powerful, grid-based system for crafting two-dimensional layouts. CSS Grid Layout is a modern CSS module that gives you control over both rows and columns at the same time. Think of it as creating a blueprint—a grid made up of intersecting lines—where you can neatly place items wherever you want. Instead of battling floats or relying on nested flexboxes, Grid allows you to describe your layout in a declarative way: The browser does the heavy lifting. The code is cleaner and easier to maint…  ( 8 min )

What Really Happened in the AWS US-East-1 Outage and Why It Was So Bad: An Initial Writeup Based on AWS Communications While many tech professionals have detailed AWS’s recent US-East-1 outage, my view is shaped by extensive experience managing DNS outages in on-premises environments. This writeup is an initial analysis based on AWS’s official statements and public information. DNS outages are a fundamental failure point in any distributed system. No provider, including AWS, can fully eliminate DNS risk. Yet in on-prem environments, DNS disruptions—even with tight application dependencies—usually recover fast and stay localized, enabling quick service restoration. AWS operates at hyperscale—millions of interdependent APIs, services, and control planes deeply coupled and globally dispers…  ( 9 min )

When we build APIs or services that accept frequent requests — like a website analytics tracker, login endpoint, or public data API — we eventually face one of the oldest scaling problems on the web: what if someone calls it too often? That’s where rate limiting comes in. Rate limiting is the practice of controlling how many times a user (or client) can perform a certain action within a defined time window. It protects your system from: Accidental overloads (like retry storms) Misbehaving scripts or bots Denial-of-service attempts Excessive costs (for APIs that bill per request) In short: you decide what “too much” means, and then enforce it gently but firmly. Every rate-limiting strategy is built around three questions: Who are we limiting? (A user account, API key, IP address, browser…  ( 8 min )

Hi, today I want to talk about how I expanded my CLI tool’s functionality by analyzing another similar open-source project, Repomix. Before diving into the code, I wanted to get a sense of what the project actually did, so I started with the web version. The visual interface helped me understand its features a lot faster than just staring at files full of unfamiliar code. After experimenting with the web version, I noticed several useful options: you could compress code, remove comments, and strip empty lines. These features seemed really practical since I often use my own repository packaging tool for personal projects, and even after packaging, there’s usually a lot of irrelevant content left. I really liked how Repomix handled this problem, so I decided to see how it implemented these f…  ( 7 min )

State Updates Managing arrays in React state is a fundamental skill, especially when dealing with dynamic data like a list of users, products, or, in this case, selected items. While array methods like map are great for updating every item, what happens when you only need to change one specific entry based on an ID or name? That's where the JavaScript method findIndex() shines, particularly when paired with the immutability principles of React state updates. This post will walk you through using findIndex() to locate an item's index and then safely update that item in a TypeScript React application. findIndex() Over find()? When you need to modify an item in a React state array, you can't just change the item directly. React demands immutability: you must create a new array with the up…  ( 9 min )

🧠 Discussion post Many major breaches weren’t flashy zero-days — they were long-dwell intrusions where an attacker lived quietly inside the network for months or even years. For anyone managing infrastructure or doing security work: What’s the biggest blind spot that lets attackers stay undetected for so long? Here are a few ideas I’ve heard from practitioners: 🔍 Limited visibility or incomplete telemetry 👥 Weak identity / credential hygiene 🌐 Flat or poorly segmented networks 📜 Incomplete or tamperable logging 🧠 Or maybe something completely different? I’m exploring how containment and audit automation could shorten dwell time — still in the probing phase and looking to learn from real experiences. If you’ve seen long-dwell attacks first-hand, or built monitoring/segmentation that actually worked, I’d love to hear what made the difference. 👉 Drop a comment with your observations or favorite tools — I’ll summarize the best insights in a follow-up post.

Last week, I started a new series documenting the journey of building Disco, a more effective networking app for in-person events. We also formed our first pilot partnership with York University, which helped validate the idea early on and gave us real-world feedback to shape our next steps. For the past two weeks, I've been building Disco with two friends. A small, scrappy team that believes in the idea as much as I do. As I started sharing about Disco more, demoing it at friends' parties, at the Startup Open House event that recently took place in Toronto, and even to incubators such as the DMZ, new ideas kept coming in and the feedback was amazing.
